87 TBI connector questions

[87TBIguy]

Hey guys just got a few questions about a few unknown ( to me) connectors, hoping somebody could tell me where these all go. Pics are attached, sorry for the crappy picture of the black single terminal connector, this is on a long black wire coming from the fuse block.

Can you tell us what the wire colors are for the pictures? They are kind of hard to pick out.

pic 1 is a long black wire, coming from fuse block, long enough to reach the nose.

pic 2 is a tan? wire coming from far right connector in firewall

pic 3 is a single tan wire coming from a gromet in the firewall, havnt traced this one back yet.

pic 4 is single green wire breakout from the main engine harness

I'll take a look through my 87' wiring diagrams and see what I can come up with. You'd think this info would be burned into my brain after doing a TBI swap into my 84', lol.

Awesome thanks, I know I've looked through all my 87 diagrams and could find a thing, I hope youve got something I've missed lol

Hmm still not really seeing anything that looks right. Also the black wore to the starter, what terminal for that?

I'm having a hard time matching these up as well. You'll probably need to end up tracing them with a multimeter.
