Wondering if anyone can help me with identifying the plugs on the headlight harness? I have the ones for all the lights ok but there's a few that plug into boxes I know there are airbag sensors but there's one behind the passenger side headlight I have no idea what it is... Any help would be great thanks
Awesome thank you so much not sure what c122 and other numbers are in there but should be ok. If I deleted the smog pump I should be able to do away with the thermactor air diverter and bypass solenoids correct?
C101, C121, C122 are connector location from one wiring harness to another.
Yes if you delete your smog pump you can get rid of the Air Diverter, Air Bypass and all the other smog related parts. Just make sure you cap/plug any vacuum lines
When you delete your smog pump without the extra air, the catalytic converters will clog and fail.
EGR is for emissions control and fuel economy so you won't pick up any additional mileage by eliminating it.
I've read many times that you can remove the EGR simply by unplugging it and blocking the EGR port down at the cylinder head, or at the upper and lower intake. You will get a CEL however because code 33 will trip the light. DO NOT install resistors. You want the CEL to tell the ECU to disable the EGR function. If you trick the computer into thinking the EGR is in place and functional, you may find you run lean at part throttle cruise. Not something you want. Proper way to then tune it out is to get a custom tune that turns off the EGR function permanently. Then, you install the resistors to turn off the CEL.
I have a bama chip but I think I'm going to just leave the egr for a little better gas economy I've read the gains aren't anything either way so might as well leave it, you wouldn't happen to have a diagram with the vacuum lines would you
Not sure I'm still working the harness but know imma have to do that next and was looking to get a jump start lol the engine was pulled and completely overhauled so I've got a lot of work ahead of me and being my first build I'm learning as I go so thank you for you advice
