So i am at a loss on this one...
I had a 2015 ram ecodiesel loaded with every option available and one of those was the 120v outlet on the dash. One of the wires running to that outlet is a white wire w/green strip and it happened to come live (12V DC analog) when the headlights were turned on. I ended up using that initially to control my HIDs in my 2015. The downside was that the HIDs would come on with the parking lights also which was fine but eventually irritated me because when you remote started the truck they would come on... So i went searching and ended up soldering a wire directly to the headlight switch on the dash. There was a pin for the low beam that came active with a 12v negative analog signal and worked great, the lights functioned perfectly and the TIPM module had been bypassed via a simple relay that was just wired for a negative signal...nothing to it.
Now on to my 2016... i now have myself a 2016 ram 3500 cummins. I decided i wanted to throw some LED headlights in it and immediately thought i could solder on to the headlight switch again like i did on my 2015. Soldered on to the exact same spot and what do you know, it DOESN'T work. I tested the spot and every other spot i could find on this truck and it seems Ram has dropped the power running through the headlight switch now to such a minimal amount that it can't active a relay....and my other problem being that i do not have the 120v outlet in this truck so i can no longer use that as an alternative...
I have spent hours testing the circuit boards and wires etc..I have yet to find a 12V (positive or negative) analog signal that comes live with the low beam (or parking lights for that matter). I DO NOT want to use the retrosource harness as right now the conversion from CDN to USD is terrible, not to mention its $100 USD for a part i feel i can avoid using. If it comes down to it i will bite the bullet and just buy the harness..although the harness only has a 50% chance of working on the 2500/3500 trucks.
So long story short.. Is there anyone out there with a 2016 that has managed to bypass the TIPM module to control the low beams via relay? Every wire or circuit i can find on this truck is negative and uses a digital signal so it upsets the TIPM when you tap in to it. I have no problem soldering on to the circuits in this truck and voiding warranty. I just simply want to bypass the TIPM for the lowbeam control without buying a (currently $135 CAD) harness..
If anyone has any ideas it would be greatly appreciated. I know what some will think "why not just buy the TRS harness"... I will do this as a last resort if it comes down to it, but the harness still only has a 50/50 chance of working so i would rather just find a simple way to bypass the TIPM like on my 2015..
Thanks in advance for anyone who actually followed that and can help! I did manage to bypass the TIPM on the highbeam already in the 2016, just the low beam that is kicking my a*s.
