Yet another one from me - Difference between Yellow/Grey Body harnesses

[spipedong]

Hey guys,

This is the last engine swap I'm going to do, and I'm being very thorough in fixing things I'd just let go before...

So without further delay, does anybody have a specific list of differences between the grey/yellow body plugs?

This car is my first 89+ and it has grey plugs, however the yellow harness I had from my 88 plugged right in. Now I notice that the oil pressure gauge and fuel gauge don't work. Am I correct in assuming these go through that harness and may be misrouted even though the plugs were identical, or did I just happen to have weird plugs that were mismatched color?

89s have mixed pre 89 connectors and 90+ but they're grey in color.. pinning is the same on them (pre 89 style connectors are the same pinning and same for 90+)

That's the confirmation I was looking for. I was pretty certain the 90+ harness had more pins on it, and if mine plugged in it was right.

Thanks!
