So, I have been on one hell of a journey with this car, trying to get it upgraded, and now trying to fix whatever went wrong while I was upgrading it. I did a cam swap recently, and I was able to successfully change out the parts and start the car, however, I must have done something in the process that really messed stuff up because it is still throwing a bunch of warning lights. I sent it to the mechanic and they changed out a bunch of parts, but my traction control light, ABD light, and check engine light are still on. The CEL came on otw home, so I haven't had a chance to pull the code. However, the car seems to run just fine, and everything is working (aside from needing a tune), but I would still like to clear the lights if possible.
The shop changed my power steering pump and brake pump, which fixed some of the issues I was having, but they were unable to clear the code entirely. They brought a specialist in to scan the car and found all the fuses to be fine, but for some reason the ABS doesn't want to communicate with the car. Their best deduction was that it was a ground wire located in the back of the engine labeled G105 (I've attached the info they gave me about this). Any ideas where this is at? Or, any ideas what else may be causing all of the lights to come on? I planned to get it tuned soon to level out the kinks, but I would like to clear these lights eventually, just for peace of mind if nothing else.
Parts changed:
Camshaft (with rockers, rods, springs)
Power steering pump
ABS module
Cooling fan assembly
Problems:
ABS light (on and off intermittently)
Traction Control light
Check Engine light (I will add the code when I get home)
For ANY module "no comm" the first thing is to check all the power and grounds to that EBCM module and data network also...was that done ??...and yes, that sounds about right...these idiots just replace parts and hope for the best...is this something you are going to try and diagnose yourself ??...if this testing is over your head find an auto electric shop in your area.

They did say they looked everything over, but they said the ground wire was difficult to get to. I need to get an owners manual to find out where the ground wire for the ABS module is, but they said it was somewhere near the bottom driver's side of the engine. I am trying to diagnose it myself, as I have already spent more than I have on the mechanic visit. I can't afford another multi thousand dollar repair atm. I was hoping someone here would have had a similar experience and see what they may have done to fix/diagnose the problem.
This is NOT in the owners manual…you need Service Information like Alldata…I think you should find an auto electric shop…most “mechanics” I have met over the last 50 years are VERY poor with anything electrical…mechanics just change parts…how much electrical diagnostic experience do you have ??…please understand that what worked for someone else may not work for you !!

I'll look into finding one in my area if my labor bears no fruit. I'm not going to get in over my head with diagnosing, but I do want to try to save the extra cash. Thank you for the guidance!
Check the G105 ground—it’s on the rear driver-side cylinder head near the firewall. Make sure the ring terminal is clean, bare metal, and tight. Also verify ABS module and wheel-speed sensor connectors, plus the main battery grounds to frame/block. Pull the CEL code when you can; a U- or C-code will confirm a communication or ABS fault. Those three lights often clear once G105 is cleaned and tightened.
Where did you get your service info saying G105 is on the rear drivers side cylinder head ??…also just checking that a ground is “clean and tight” is not how a ground is checked…what if that ground wire is broken 1 inch from where it’s bolted to ??

Okay, I'll get back there this weekend and check it to make sure. If that clears everything up, I'll be in your debt, lol.
You need to checks both powers and grounds…you can check these with a headlight bulb and NOT a DMM…below is EBCM pinout so you check anything that says battery positive voltage and ignition power and both grounds…if you are not familiar with how to test these and how it is done with a bulb see a specialist.
Where to begin?
