I need some photographic help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

joe231 · 05-14-2010, 11:07 PM

As some of you might know, I'm retro-fitting the entire harness and TBI set-up into my crew cab from a '89 'burb. I am trying to figure out all the routing and some of the wiring. The PO of the 'burb cut the ends off of some of the wiring, including ground lugs and the alternator plug and eyelet. I could use some under hood shots of the wire routing (89-91 Blazer, 'burb or crew) as well as the wires running to the alternator and the power junction block located on the firewall above the brake booster.
thanks in advance guys (and/or gals

)

see if any of this helps, I have alot of extra stuff because of the airride but here are some pics

joe231 · 05-15-2010, 12:58 PM

Cool
thanks!
Where does the heavy wire in loom coming off of the back of the alternator go?
And what color are the 2 wires that plug into the alternator?

justpball · 05-15-2010, 01:50 PM

heavy gauge goes to the battery and the two small gauge are black and red with black stripe

joe231 · 05-15-2010, 02:27 PM

joe231 · 05-15-2010, 07:10 PM

What year are the pics from?

justpball · 05-15-2010, 10:38 PM

1990 burb

joe231 · 05-16-2010, 12:12 PM

I was just wonder because your colors don't match anything I have or the diagrams i have.....

*Stitch* · 05-16-2010, 12:41 PM

my crewcab is an 87 and it had TBI in it...give me a few and I'll go take some pics of the harness for ya...it's still in the truck...

edit: went outside to the truck and the wires were cut to the alternator...also, there was one large red wire w/ ring terminal and one smaller wire with a two hole ring terminal on it going to the junction box...

in the first picture you can see those two wires on a harness I have from a burb...dont' know what year though...

also, the second picture is of the wires that are coming out of the burb harness where the alternator would have been...the wire colors are from left to right...blue, red, purple, black/yellow stripe, yellow...

hope this helps...

*Stitch* · 05-16-2010, 03:29 PM

the black and white is ground, the only larger purple I know of goes to the starter solenoid, the blue I'm not sure of, does it have a stripe?....and the last wire, is it white or tan? does it have a stripe?
