Well finding out all these abbreviations I have a L76 6.0 alum shortblock, (58 reluctor wheel) with no accessories, and a set of CNC LS3 heads. I found a LS3 intake complete minus t body and see they are fly by wire t bodies and I want a cable (for my Mustang) Now the biggest thing is finding what harness and computer I can use to make it cable driven. On my old LS1 it was easy as I was able to buy a ported throttle body but looks like no luck for a LS3 unless one of the other LS bodies fit. Same goes with the harness, it was just a 98 Trans Am. Frustrating as I just want to finish this car to go to other issues. Heres my old car, it was LS1 stuff and a lot easier. Now I have a nice black coupe to go under the knife. been hard as my wife just past away last week and I just want to finish this and be done with it before it ends up sitting forever if you understand, I think I'm ranting now.

You'll probably have to talk to a tuner. The L76 is DBW. It's not hard to integrate the pedal into the car though. I did it and it only took a simple bracket.

ahh dbw "drive by wire" lol, learn something new. Thats the problem I want cable. So I'm trying to find out what harness to use as the L76 doesnt know whats on top. Should have listened and just made it carb.

L76 has a 58x reluctor wheel which means you can only use a newer ECM. The newer ECMs can only read DBW, not DBC. You can change your crank to one that has a 24X reluctor wheel and use an older ECM that can accommodate DBC.

motor just picked up, so changing really wasnt an option. I was under the impression that some suvs and trucks used DBC that where 58's and then can have it tuned. So maybe I'm being misinformed when I just bought this motor today. Had a chance to buy a iron 6.0 with 24 reluctor, but was trying to be light.

wow, really screwed, I also ordered today a complete minus throttle body LS3 intake so not sure what I'm going to do since now that I'm researching it you guys are def right. I usually read up on it but with my wife passing and wrong advice today I was in a hurry to finish the car. lesson learned, car is being parked. thank you for the info.

after long read, maybe dbw is not so bad, so ac delco 217-3153 is the throttle body needed and a harness from a 2010 2011 camaro . Now how do you do the pedal?

Bowtiedford

I see the lokar unit for DBW, so what engine harness would be a needed. the Lokar unit doesnt list a camaro

ok so looks like I need a TAC module, Gm DBW pedal assembly. Now if I get a engine harness like a corvette does the harness go to the Tac module or somebody said it goes to a dash harness? and then to the pedal assembly. little confused.

oldgoat69

Which PCM do you have? The later style E38 or E67 do not use a TAC. A much less expensive alternative is an OEM pedal from a Corvette or truck. The LS3 TB is already 92mm so it can handle a fair amount of air. Yuo do need to pay attention to the harness you get. Make sure it will actually match the PCM in regard to # of connectors. I have recently seen new take off throttle bodies for $109.00. There is an ebay guy that had a whole bin full of them. You can also use an LS2, but the cost is far greater. I have proven that you can use the less expensive unit as a substitute.

no electronics as of yet. So far the L76 6.0, LS3 heads, LS3 intake with inj and the t-body thats DBW its an ac delco 217-3153 seemed like the one everybody was using. I havnt bought anything yet as very confused on what. Did see corvette pedal

this harness

my tuner said he can flash any pcm ecm computer lol. just wasnt sure of the swap parts.

oldgoat69

Be sure to get a PCM compatible with 58 tooth reluctor. Then just match the pedal to the PCM. The early 411 ot GMT0800, even the E40 will not work. There have been a few listed in the classifieds here recently.
maybe check here http://www.pro-touring.com/threads/9...body-DBW/page2

Since your dropping some coin on this project, then you might as well order a harness and ECM from a vendor. If you tell them what you have, and what car it's going into, trans, etc, they can make your harness, provide the correct ECM for your application, and most likely include a pedal . I'm ordering one for my swap based on the info I gave them and it cost $1700, for custom harness, ecm, pedal and trans controller. Saves me the headache and time of cutting and splicing a donor one. My Monte LS Swap I used a GM ECU and transcontroller. That cost more than $1700, and the harness was a once size fits all, meaning it was really long in some places and was difficult to make it looked polished. The GM Supermatic Trans controller was a pain as well. If you can afford it and not want to waste time, then get one made from a vendor with your application.

oldgoat69

That is the blue/green PCM used in trucks 03-07. They are all for 24 tooth reluctor and as far as I know are DBW.
If you know what you need to start with you can go to www.car-part.com and find the individual components. I would suggest that you start with a single vehicle application such as a 07 Corvette and go from there. Pedal, PCM, wiring harness, and then pick a 6 wire throttle body.

thanks, now i know those numbers are PCM's. Thats exactly what I'm going to do is get everything together from 1 donor vehicle.

when I did my LS1 car, I realize why it was so easy as we had a totaled 98 Trans Am in front of us.

was going to buy what was listed on the previous above post on ebay since its corvette pedal and harness but when i called them about where the pedal harness goes to they said into the dash. The engine harness does not go to it. so I might pass on that stuff.
