Mostly I want to check to see if I'm doing my swap right, and I need some clarification on a few wires, I know this might be a bit redundant but I haven't had any luck finding it online.. So..

 

I followed numbachuck's (spelling) guide the best I could, this is what I have..

 

86 subaru brat, ej22 engine and keeping the brat manual transmission, harness was done by SJR.

Also got a complete wire diagram from a vender online.

 

Ok, I have the speed, tach, oil pressure, coolant temp, going to the dash display, I have the "hot at all times" going to the battery with a 15 amp fuse on it.

 

Now the things I don't understand,

 

1. Starter wire, the ecu has a 18 gauge, and the starter wire from the brat side is a 10, is it ok to splice them together?

 

2. I can't find the check engine light wire, the wire diagram says its blue/red, with a black/white (ground?)

But I can't find a blue/red wire on the white round plug terminal.

 

3.i have a few wires labeled "hot fused" should I also have these on the wire coming from the battery, is the fuse size the same?

 

4. One for "hot run and start" I just don't know where to put this...

 

I think I have a handle on everything else, I didn't dismantle the car, but bought it in boxes, unlabeled and unorganized, so guessing where parts go, and having parts that I have no idea where they came from has been a challenge, but I thing this Brat is getting close to being driven.

Hot run and start sounds like the Ignition Coil wiring on a Brat etc.

 

Starter wire only operates the solenoid at the starter so as long as it's getting proper 12 volts should be OK

 

Hot fused I assume just means 12 volt power possibly Ignition Key switched not necessarily always powered that could cause problems with flat batteries.
