Complete mechanical overhaul

I have a 2013 tundra SR5 crew max. I’ve had it for 3 years. Within that time I probably havent put 3000 miles on it and I’m finally putting some money into it to get it back in good condition. I guess the people who had it before me didn’t care too much about doing things the right way, because I’ve already put about $2,000 into it within the last couple months and every time I go to fix something I find something else wrong. I’m in need of detailed wiring harness diagrams for the audio, master window switch, and the a/c wiring connections. Also I can’t figure out how to get my traction control light to go off, the airbag light stays on, tire pressure light is on, 4x4 light flashes.

This is everything thing I’ve done to it since the beginning of March.


New spark plugs

New mass flow air sensor

New control arms

New upper ball joints

New lower ball joints

New tie rod ends

New suspension stabilizer bar links

New K&N filter

New throttle body gaskets

New battery connections

New center console organizer

New front end alignment

New stock exhaust

New window master switch

New fab tech shock bushings

New brakes

New gas cap

New Fleece Performance All Lights On

New A/C Refrigerant Liquid Hose

New windshield wipers

New tires

New front lug studs

New lug nuts

New battery

New rear end

 

Airbag light could be the clock spring. Does horn work? Steering wheel controls work? Cruise control work? If none work replace the clock spring.
Tire pressure light could be anything from dead battery in a sensor(requires sensor replacement) or no sensors at all or replaced sensors that were not cloned with the original ids or the the new ids were not written to the ecm.

 

The steering wheel controls work and the horn kinda works. If you push it the right way it’ll sound.

 

You did all that work for $2k!? Where are you sourcing parts that cheap?

Beware... All lights on may be a fire hazard. Not saying it is, just saying you might want to be prepared just in case.

 

I did all the work myself besides the exhaust and the a/c. I bought most of it from Amazon. The ball joints I got from oreilly’s

 

Can someone please post a picture of the wires on the sensor to the a/c liquid refrigerant hose? The wires on mine have been pulled out of the plug and idk which one goes where or if these wires are the correct ones.

 

I sent you a link above to the wiring diagrams. Wire colors are on the diagrams unless someone modified the harness. It should at least get you started while waiting for a photo.
