Arrggghhhh!!!! Wiring, and what in the hell did I forget to put on my trans before I put it in the truck? I swear I took better pictures of where & what the wiring harness connected to, but clearly I didn't. The wiring harness shown is from a truck that was being parted out. Mine was literally bare wires. To the starter correct? And obviously I am going to have to replace the fuseable link? Any ideas where this pig tail goes? Looks to be from starter to ??? Wires coming off of the alternator. I have no idea what they connect to as the "new" wiring harness doesn't have an obvious plug in for them, or the same colored wires. How hard is it to turn truck into a 1 wire alternator? I can look it up I reckon. Pretty sure there are parts missing here on the transmission, the small "hook" thing in the approx 6 o'clock position of the picture: Getting much closer to getting this thing up and running. Thanks in advance for the help.
Yes the first pic that is the harness from the positive batt cable/post on the starter to the junction block on the firewall with fusible link protection. The hook thing on the trans is for the Throttle Valve cable. That bolt next to it holds it down on the case and it's sealed with an o-ring. I know the pink wire on the alternator goes to ign on feed. Not sure about the tan one. A larger fused wire goes from that big post on the back of the alternator to the junction block on the firewall.
If I remember correctly the brown wire on the alt is the exciter wire. Goes to the alt bulb on the dash panel or the gauge on a gauge cluster. One wire alt is cool but the three wire works better. Good write up here http://www.madelectrical.com/electricaltech/onewire-threewire.shtml
Thanks, looks like the service manual, more wire, heat shrink, and I are going to become very good friends here in the near future. Thanks for the link. I had considered a 1 wire alt, but think I'll stick with the 3 wire. If anyone has pictures of their wiring harnesses I'd be most appreciative to see them.
I hear you on projects that take forever, I haven't really had the time to mess with my truck in months...
Been a while but I am back. New transmission in our 1991 Suburban, and more importantly today...........The new wiring harness, transmission lines, air filter & housing, battery going in. Pics to follow if I don't get mad and hammer toss the camera when the frustration level peaks. What? Like I'm the only one that's happened to?
Hahaha...I understand completely. No pics yet, but on Friday we (my sons) and I got her to fire up for just a few seconds. Open exhaust, a 350, and in a garage.... Like angels were singing. Anyways, kind of a boring post, but I'll get some pictures posted hopefully on Monday. Just nice to be making some forward progress.
