I have a 2005 6.0 with the dbw throttle body,
Which engine harnesses are compatible with this engine?Will a 5.3 harness work from the same year?I am having a hard time finding an engine harness for this engine from my local salvage yard.If someone has one that will work I am shopping for one,
Thanks

Youll need one from a motor with a 56 pulse crank trigger, instead of a 24 pulse one, if your crank trigger is gray instead of black, which it most likely is.

58x pulse my friend from NEPA (can you send me some Middleswarth BBQ chips?!).

Check the sensors or reluctor wheel style first. I know some 05's had the older 24x, I thought 06 was the main change-over year for the majority. Like posted, black cam/crank sensors is 24x sensor, gray is 58x......unless someone pulled a fast one on you.

Check with some of the conversion sponsors, Speartech I know will have something, maybe Painless...

Yea thanks, I never checked what I typed, it was late and I'm old. Plus my eyes were burning from the Av gas from being at Numidia all night. I was helping my buddy's kid Steve with his 410 1st gen smallblock in his S10, he had it down to a 11.33 in the quarter mile, before red lighting out. I keep telling him, he should have built and LS based motor LOL

PS Do you really want the chip? I haven't seen them in a while, but I'd look for you. Personaly I think Golden Sun were the best, but they've be gone for a long time

Wow... the 58x didn't start in any of the trucks until '07, so don't worry about that.
If you want to keep the drive by wire, then just find a drive by wire V8 (4.8, 5.3, 6.0) harness from any '03-'06 (and early '07) trucks.
They are pretty much all wired the same. Only differences are flex fuel injectors vs. standard, 4L80E vs 4L60E, and 4wd vs. 2wd.

The sensor in my 05 Hummer engine is black...

I have an 06 Tahoe 5.3L engine and harness that has Gray and 58x. I'm sure 05 is 24x.

Thanks everyone,
The crank sensor is black.

Really you can use any harness from 05 and earlier. The main differences between harnesses will be a few connectors, usually just fuel injectors, O2 locations, EGR, etc., and if you're changing the intake to an LS1/LS6 type you can use any F-body harness or f-body derived conversion harness - which seems to be the most popular route if you don't have one already. The f-body harness would make it necessary to ditch the DBW TB, although there may be a C5 harness/SBW module solution offered by someone, I would definitely check with Speartech if you want to keep DBW.
