just bought a 91 syclone with an engine from another crashed syclone with 60k and 5k on tranny evrything is in and bolted .. but it needs the harness connected and i bealive the starter is missing im pretty handy so im pretty sure i can do this.. but i can not find any diagrams on how the starter is wired currently the truck has the battery in the back with cables already ran but not connected to anything not even alternator so basicly there are no wires connected to the engine they are all there except for the injector harness which it took 3 days of intense reaserch and got nothing so i talked to my bro that works and owns grandnationals and he reffered casperselectronics.com so ill be ordering the beefed up harness they make soon but i wanna get started on the rest of the wiring iam not in a rush but i am eager to drive it...:tup: so if you can shed some light on my wiring situation that would be great thank you i will be taking pics of engine bay today and posting tonight for now heres how the truck looks

Welcome! May put the last 4 digits if your VIN and register the truck with http://www.sportmachines.com/members/register2.php

Wiring diagram: http://www.tyguy.net/gmc_oemparts_elektrik.htm though I dont see the starter called out.

I just did mine and its pretty straight forward. Tight squeeze in there and had a heck of a time wiggling it out there. If you use the Forum Search feature there is good info on how to do it (should remove the wheel).

Welcome to the site. Where in So Cal are you located ? Your hood look like the WS 6 TA hoods. Nice wing by the way.

Click to expand...

I think most on here use a stock coil, you will want to replace the rotor on that distributor too. Use a good brass terminal cap.

Be VERY nice to the shy guy, his knowledge is invaluable. Unfortunately, many figure this out too late...Jim
