So here is my problem, there seems to be quite a few wires that are all miss matched and don't connect. I'm sure some of the wires don't matter because the motor going in had AC & cruise, the 86 truck didn't, but I don't know the wiring for that, anyway it seems there is no spark to the injectors, and it seems one of the wires not connected is to the injectors. And also when we turn the key in the truck it doesn't turn over, we have to hit something on the motor I forget to get it to roll over, of course it doesn't start.

So can someone just point out the wiring in a 86 & 88 ranger, and what the wires that MUST be connected look like. Cause I really don't want to have to take the truck to a shop and have fixed, spent to much money on it already. I just need to know what wires are what, if someone could maybe take some photos, it would help. I could even take a few photos of the wires I'm talking about if that would help.

I have the book for it and all that, but that doesn't seem to really help at all. I'll post some pics of my problem later today, to make it easier for someone to help. Thanks for any help!
