Smallport harness connector identification help

Postby Rogue-AE95 » Sat Mar 16, 2013 12:49 pm

So about a year ago I pulled what I could from a 1990 Geo Prizm GSi with a smallport 4A-GE. Smallports are rare in my area, in fact I haven't seen one in the past year, and I don't know anyone with one running in their car to get info from. The last thing I was trying to get was the wiring harness, as this 'yard doesn't keep cars for long, but it was near closing time for the junkyard and I had to cut the harness to get the connectors. I didn't think it would be a big deal since at that time I was planning to use a chipped Honda P28 ECU to run my 4A-GE build... but I did manage to get some of the more important connectors like TPS, distributor, etc.

Now I'm going to use a Megasquirt ECU, but I'm still going to have to build my own harness. I have a few mystery connectors that I can't identify... help? I've numbered the mystery connectors to make it easier to identify (1-5).

And finally, a question. Should I do the same when I make my own harness?
