Thread: 99 g20 wiring

to make it simple, im wondering if a b14 style wiring harness will plug in under the dash. i got my p11 cheap with a chopped up wiring harness and im trying to replace with a b14 one, or a b13 one. wondered about the underdash plugs and if a 99 sel/g20 harness is the same as the previous year b14/p10s?

If I recall correctly 99 G20 should be the similar as 99 SE/98 SE-R.

yeah i figured it would be at least the same as a 99 sel/se. basically im considering boosting it and swapping to 5 speed. the factory auto wiring is a mess, kid cut the harness to get the old motor out, DO NOT ask me why. hes a complete tool. what im wondering is if i find a regular 95-97 b14 harness will it plug in under the dash? just trying to avoid a bunch of repining/splicing under the dash. For some reason i just figured the 99 would PROBABLY have the same under dash plugs off the wiring harness.

If it's an auto, I would just get an engine harness and call it a day. Also now would be a good time to go to OBD1 if you can

yup thats what i planned. im actually just putting it back together to sell, and as theres no catalytic converter, figurerd it would make life easier obd1 lol. just got to figure out the under dash plug wiring. guess it cant be too hard.

99 harness is the harness to have if you own a p11. I know a p10 harness doesnt directly plug into the chassis harness. I dont know about an se-l harness. The 99 harness is compatible with the newer 32 bit ecu's and the older b14/p10 ecu's by switching a couple pins.
