420a/NT PCM wiring info

[kergilman]

I was looking for information on the ECU pinout for my 99 GS but wasn't very sucessful.

I did see this recient posting which is an excellent harness end reference: http://www.dsmtuners.com/forums/420a-bolt-tech/283950-2gnt-pcm-connector-views.html

And this one seems to lead to something, but the links would not load: http://www.dsmtuners.com/forums/420...-look-here-1998-only-ecu-pinout-diagrams.html

My Apexi turbo timer & W/B O2 Zt-2 arrived in the mail and I attempted to scope out the required wiring work. Looking into the drivers side kick panel, instead of an seeing and ECU and harness (as you would seem to w/ a GST/GSX) I see 4 connectors, mounted horizontally, seemingly using that area as a harness disconnect point. Since these connectors do not seem to pinout identical to the standard 2G reference connectors I see pasted everywhere, I was hoping one of you 420-t guys might have this info stashed away for future reference if these are indeed inline of the harness. (I would post pics but left the camera at the shop Sunday...)

I did get that Bosch O2 harness through a hole I drilled just above the throttle peddle mount which was a biiiiiotch...

(This should probably be in the 420a Engine Mgnt section...if so could someone move it for me..?)

Disregard. I found my only option was to tap the ECU harness just below the 2 x 40 pin connectors in the engine well. The 4 connectors behind the stock stereo that I had in question are not the same as the 4g63 harness connectors found in the same area (The connectors look similar but are short a few pins to match the standard 2g connector reference eveyone uses).

I did find a little more harness information over at the 2GNT site for my 99 GS model wiring...well, enough to confirm it was safe to tap the top harness pin 10 ground and pin 30 front O2 signal for my Apexi TT install.

The Zietronix is next. I installed it just inside of the kicker panel with a slim terminal block(radio shack) to organize wiring.
