Alright, quick backstory so you know where I'm at... Got a 2002 IS300.

Just did a entire batch of maintennance - Oil pump, front main seal, timing belt, timing belt tensioner, water pump + housing, thermostat.

During the time it was down, a battery was hooked up backwards and yeah... Pop go the fuses, time to trace down the issues. Replaced all the popped fuses which included ECTS, among a bunch of others, checked the rest with a meter. Here's a list of what's left...

Rad fans won't kick on.
Fuel pump gauge doesn't work.
Climate control won't kick on.
ABS light is on.

Car runs, drives, feels great, doesn't overheat driving around normally (only started creeping temp one time idling at a light in hot weather), zero driveability issues, feels great comparatively before the work.

I don't know how to verify the relays as they are a 4 prong - which pins should I be feeding voltage to? I don't even know where to start with the fuel gauge - the low level light just blinks which I was told means no signal from pump.

Any ideas?

I'd replace all the relays just to be safe.

Did you have the codes checked?

Ill have to pull the codes - haven't done that yet.

I figure I should just replace all the relays in the car anyway as there is a chance that if they havent failed already, that they might once I get everything set up again 100% and get proper voltage.
