OK

I thought I would be able to do this on my own, but I guess I need some help

Anyone here ever wire in a APEXi RSM ? and a PRO ECM Powerchip ?

I have both and I want to install'em but every place I get info from is different and I don't want to fuck up since they wire up to the ECU

The Pro ECM chip is a dedicated "bump" chip. It intercepts the ignition timing and makes the ECU think it's running rich and then the ECU retards the timing making it run a little leaner. It should install pretty much the same way it does on the Impreza, but I've heard really mixed reports on results. Most people have discovered that piggyback ECU's don't work on the 95-01 Subaru ECUs unless you're at WOT, which makes them useless for anything other than drag racing.
