I rigged up a way to get the codes out of the ECU since mine doesn't have a LED's on the ecu. I got a code 12 (MAF) Now When I wired the car up with the 8 step program. I was never able to find this conector http://azparttrader.com/rbhelp/IMG_2518.JPG

The one that the grey wire goes into. So I just ran that wire to the white Dash conector inside the car. Just so you all know this is a series 2 motor so the coils are fired from the ECU. The engine starts up fine but if I give it any gas it cuts out like I am hitting a rev limiter.

I fixed the problem! When I cut the shielded wire to pull the wires out I must have sliced into the one signal wire and the grounded shield wires touched it. After fixing that problem the engine revs up right now and isn't running as rich. Is the DP coming soon?

I am also going to have to make a new O2 sensor housing. The stock one still makes contact with the steering shaft even after grinding all the way through it. lol. I am getting a flange made for the turbine outlet.

GOOD JOB!

I am glad it's working for you now!

The motors run super rich stock...kind of safety setup. I had to clean my exhaust every week and it was black by the time I cleaned it again.

Get ahold of me now that it is running and we can get your gauges all set, if you need any help that is.

Congrats!Jon

I made up a chart with the S13 gauge wire colors and the R33 next to each other and what they do. I guess I need to run some extra wires for the Oil gauge and boost gauge. The one thing I was wondering is the illuminaition control. Does it work the same as the R33?
