Swap wiring question,88 harness in 86.

I got another wiring question for ya. 87-88 5.0L harness in 86 car. I know I need to make a conversion harness for the connectors that do mate, but is it safe to assume that the matching color wires go together. I'm talking about the 2 connectors next to the brake booster on the main engine harness, and there are different style connectors on the car harness, so they do not mate. Can I just match the same colors up and be set or not.

'Cuz I know sometimes the same color wires are used more than once, and I'm havin a hell of a time findin some of them in the EVTM, and am not sure what some of them are for. Then tryin to track down where they go is kinda tricky. :shoothead I just want to make sure I don't short anything. I got just about everything else figured out. Any info would be helpful. Hopefully I can get this beast fired up soon.

I'm 99% sure you can match wire colors and be OK. When I did my swap I got about half of my info from a '86 EVTM and the rest from a '87 wiring diagram. Every wire I checked were color for color.
