Did my reading and did not find an answer.

I have installed aftermarket kits before, but is there one that adapts to the LS2 electronics - like a pug and play version?

Thanks in advance
Bruce

I am thinking it already is electronically connected to the trans and DBW pedal so there should be a cruise control unit that connects to the computer and that should be all there is to it. I assume that is how the factory one worked in the GTO I goit it all from, but obviously I don't have the cruise control switches off the old steering wheel and they would look kinda dump just stuck to the dash:)

I was hoping someone made an aftermarket unit that plugged into the computer?

I can tell you how to hook the trucks PCM and TAC box up to a GM CC stalk its pretty easy. But for the GTO I can't remember if it comes directly off the ECM or is routed through the BCM to the stalk.

I'll do some research on it and see for you.

I have a LS! & 6 speed in my '56. When I cut off the wiring
that was not going to be used from the ECU, smog, and such,
I left the Cruise Wiring,, just in case.

I still haven't installed the Cruise, several othter projects
are ahead of it. Some Day/////

But, here is some info on early Vette, Camero and Firebird ECU's
that I researched. This is just a brief intro.

I purchased a used Firebird Camero Cruise module. It is a controller
with the cable and motor drive that connects to the Throttle Body.
The Cruise will need awire harness with several wire connections
from the ECU.

The ECU provides several control connections to the cruise control
module, including VSS, vehicle Speed,

As I recall one end of the double brake light switch connects
directly to the ECU.

I planned on,,,

Using a pair of the wireless modules [minature] the receiver has
several relays. My objective was to mount the wireless transmiter
on the steering wheel and power with a 9 VDV battery, a
few buttons and I'm set. The modules are inexpensive and reliable.

Then use the wireless receivers relays to interface with the Cruise
Control module.

Someday I will complete the install. It is not that difficult to wire. You can use simple push button switches and mount them anywere.

You will need a schematic of your ECU,
the BCM [Body Control Module] and
CCM [Cruise Control Module]
from the specific car your engines ECU matches. With the schematics you can develope the wiring interface.

If you decide to go this route I'll be glad to assist with the wiring
I'm an Electrical Engineer and have completed several of these and ECM mods.

Good Luck,,

Michael.

Bruce after some research it won't be easy with the LS2.

Figured out The 2005 & 2006 GTO's do not have a seperate TAC Module.
The 90mm Electronic Throttle Body has a Throttle Actuator Control (TAC) Motor built into. The 90mm ETB has only one 6 pin electrical connector which is used for the Throttle Position (TP) sensor and the TAC motor. The ECM controls the throttle.

The GTO's used the Can BUS to control the Cruise via a PIM Powertrain Interface module.

You could get the PIM from the donor and hook it to the ECM and the GTO stalk and it would work. Its mounted on the left rear of the engine bay.

You might could re-flash the ECM to another vehicles base tune so you can hook it to the correct pins of the ECM directly.

I went through the same thing trying to round up what I will need to hook it up on mine. That is with a 2006 GTO LS2 donor. This is what my local GM parts guy found by using the VIN from my donor car:

Throttle Actuator Control module part number - 10282710

On the GTO it is located behind the drivers side kick panel. I have a printed copy of the page from their parts program.

I contacted the yard that I got the car from & they still had the car. They have pulled it for me & I should have it in my hands by the end of the week.
Still not sure if it is the last piece of the puzzle or not. But the cost of a new one was crowding $500 list. So I would have went with a cable throttle body & aftermarket cruise setup if I couldn't have gotten the one from the car.

Too much confusion................

No one on any of the other sites seemed to have a definitive answer on the DBW cruise controls. And there seemed to be significant confustion when it came to the GTO's. Combine that with the fact that most of my local parts guys can't seem to accomplish much of anything these days without a VIN, I decided to try that route on it.

I am still not 100% confident that I will have all of the pieces & information that I will need to make it work but I hope that part of the puzzle is solved.

Ow, ow, ow!!!!!!!!!!!!

I read those links & my head almost exploded! Looks like I'll have to get a refresher course in electronics terminology before I get around to tackling my cruise control.:rolleyes:
 
#22 ·
LOL - I know I read all that stuff last night and ended with a head ache!!!

Well guys I may be screwed. I called my buddy and he knew exactly what the issues were. Unfortunately my harness is complete and already set up to use the GTO components so unless I want to start over on my electronics I will have to try and figure something else out. What he said all pretty much matches what the LS1tech links eluded to and what some of you mentioned.

The GTO set up does not work for cruise control. I am no electronics expert but he said that even CPP tried it and cannot get it to work reliably.

He said if I wanted to start over I would need a different pedal, trailblazer computer/trottle controller/MAF and of course a new harness made to connect it all. The parts were $400 or $500, plus the new harness. If it werent for my harness already done and I will have to pay for I would go the extra money, but I guess until someone else comes up with something better I am on hold.

I haven't given up and will still do some more talking around, a lot of you guys sound a lot smarter than me on any of this electronic stuff.

If anyone wants me to get a complete list from him and what it all might cost I will certainly do that.

Sorry I did not get us an easy answer.

Bruce I have the same problem with my 06 Corvette engine.
I bought my cruise control with my Ididit column and attached the cable to the DBW pedal, not what I wanted but that's all I could come up with. I am hoping that the signal from DD gauge will work.

BO185,

thanks for the schematic ref, I missed that post. I don't have my LS1
schmatics handy, somewere on some CD... hum.

My PIM has the motor drive and cable in one enclosure. Mine problem is that I
will need to shorten the LONG cable that connects to the Throttle Body.

I'm pre-wired. But the challenge will be dropping the IDIDIT and adding the second brake light switch.

After this short review, the Cruise Control is last on the long list of
other small projects.

Do you have a recomendation for a LS1 aftermarket intake ?? I'd
be quite interested in your take on intakes.


My motto is,,,

small projects in the Winter, drive all spring, summer and fall...

Got to keep her on the road...

Nice of you to help others !!!

Michael....

Cruise w/DBW

I'm currently having my wiring harness built by SSP Wiring in Mayer, AZ. I plan on using a '97-'04 Corvette DBW throttle body on my 2001 LS6. Should I tell them I plan on installing cruise control so they can include the proper Cruise Control wiring harness or is that even necessary?

This is all new to me so I'm in the dark (& doing a lot of research) but what gas pedal can I use for my '56? Do I have to use a pedal from the '97-'04 Corvette?

And what cruise control module (Tac Module) do I use for my application? Do I have to stay '97-'04 vette?

The CC will have to be wired in. I would call and tell them what TB and TAC you have.

A truck pedal should work with the vette TAC and TB. But I am not sure if the vettes CC is pinout of the TAC like the trucks. And I am not sure if the more common truck TAC will work with the vette TB. They should know.

TAC & Peddal Assy

B0185, thanks for the quick info. :p2:

Chevythunder.com had a really nice writeup on the DBW system. So, I will hunt for a TAC module for my corvette throttle body as well as the corvette pedal. That way the wiring harness will all work together as designed. It doesn't seem to be that bad of a mod (in theory), I will let everyone know how it turns as soon as I score the parts.

DD cruise control for DBW

I learned some bad news today when trying to install my Dakota Digital Cruise Control. My DBW pedal fits for years '97-2004. The DD cruise control is designed to work with DBW pedal in years 2005-2013. So the idea of it being a plug and play just isn't in the cards.

I called Dakota Digital and spoke with Scott (very helpful too) and he admitted that no solution exists through DD for my issue. He said he would refund me my money so that was cool.

So, back to the researching for a solution. I have 4 wires coming from my TAC module that are all related to cruise control. It shouldn't be that hard to make this work.

What year motor and trans?? Is it truck or car setup? If truck you just wire the TAC wors to the cc stalk and your good to go. There are detail ls on how to do this is here or in te FAQ sticky

the four wires are I believe the following , check with your harness maker.
set/coast
accell
torque converter signal
brake light

great news!!

Yes Hotrodg726 you are correct! And you as well BO105...thank you.

My 2004 Corvette engine with DBW setup doesn't need anything extra from Dakota Digital or other company.

I have 4 unused wires coming from my Tac Module: pin 4,5,6, 14. As it turns out those 4 wires, plus a cruise control switch are all I need to make this work. I realize I may have to use two relays to convert normally open/normally closed signals but I will test it all out this weekend. (I really want cruise for my trip to Nationals in a few weeks)

I did a write up in the ls section about how to wire in the Dakota cruise handle with relays.

I've got cruise control

I used the Dakota Digital HND-2 switch and mounted it on my console. I wanted to keep my steering column levers authentic and my console had room so it was a perfect match.

Here is a pic of the diagram I followed.
