5.3 into bravada: wiring diagrams needed ok heres the situation:
94 olds bravada smartrac with blown 4.3 whortec
swapping in a 5.3 out of a truck, with truck accessories, ls1 intake manifold, and non-dbw throttle body.
i want to modify a truck harness to work with this vehicle, but i need a wiring diagram. OR suggestions as to what harness would be easier to work with. i am NOT buying a prefab harness so thats pretty much out of the question.
im looking for a wiring diagram that i can study to see where i need to splice into the stock harness and what i can afford to lose.
any opinions?
thanks in advance

just did the swap on an 88 s-10 blazer with a 4.3 and converted to a 6.0.....little more info need and what trans are you using...? also if you use the truck harness, which i did you have to swap the injector plugs for different ones if using an ls1 intakethe injectors are different if you didn't already know that...

well its worth the time to do the intake swap cause of the clearance but your gonna have to get it tuned anyway so...i would do it....the truck oil pan fits the best....with a small notch to the crossmember 2X10...lol....my motor bolted to the adapters and the stock crossmember bolted up...the driveshaft was too short cause i used a th350....sanderson is the only company i know of that makes headers for the swap..but i used 98-99 fbody manifolds that are modified...stock radiator, ls1 waterpump, f body upper radiator hose fits perfect. The harness is easy to make if you have the time....if you want my buddy did my harness and he can mod it for you...

im picking up a pan from a hummer h3 alpha that only requires very minimal modifications. like a small notch is all really. id rather do that and maintain the stock pan as much as possible.

the alt will clear the stock hood if you use the lowest holes in the mounts....i don't know where you heard it won't clear but we have 3 lsx swapped s10 blazers in town and the alt clears the hood fine with no modifications......

the syty and bravada frames are the exact same as the 4x4 frames. the front diff is pretty much the same except there is no axle disconnect. What motor mounts are you going to use? Your running truck acc, right?
