Engine harness info What are the differences between the truck and car harness? I am swapping in a 2004 LQ4/th350 and want to know if there are any major differences between the car and truck harness for DBC(red/blue connectors). I have a blue/green connector harness and no computer for DBW and want to go to DBC.
Differences between car and truck harnesses are minimal, mainly injector connectors and MAF connector. If you are going DBC, your current harness will have to be repinned for the IAC/TPS used on the DBC application. There are Green/Blue PCMs that support DBC; specifically from 2004 GTO and Express Vans. Are you going to stick with the truck intake or switch to a car?

You can use the blue/green harness with the 0411 pcm(red/blue), only thing is the harness will need to have the dbw connectors deleted from it and you will need to have the correct tps and iac connectors added to it. Also, the o2 sensors will need to rewired for the 0411 pcm to control them and you will have to order 00'-03' sensors.
The following link will provide you with detailed info as to what all pcm's besides the 0411 pcm will work for a dbc application. http://www.lt1swap.com/cable_conversion.htm

Ok so I just found and bought a 2001 Harness/Comp 0411 from a Yukon. Do I need to buy any different sensors? MAP, O2s and I have a 5 wire MAF(85mm)? I have a 2006 DBC w/IAC and TPS from a van is that going to work with the 01 harness and pcm?
Iac and tps are the same. Be sure to get correct o2 sensors that match the harness. Was the Yukon a 4.8, 5.3 or Denali which had the 6.0? The 6.0 and 4.8 o2 harness connectors are the same but the 5.3's are different.
