Hi again guys,

I have another "small" issue with my truck.

Every time i switch on the lights i cant go more than 3000 RPMs even if i try WOT. Switch light off and truck accelerates like crazy to redline.
Found out my tail lights are extremely weak, are only able to see a very weak glow in both bulbs. So my guess is a bad ground to the tail lights, but i cant seem to find it?? Does anyone know the location of the tail light ground??
Head lights, Signal and reverse are working fine, only tail and brake light are weak??

Thanks

And by the way... Let me just give you all my sincere appreciation of this forum... Without it i guess Titan owners would be an extinct race :grimrippe

You need to look at the wiring schematic, either through AllData or another source.

Ok here is a little update...

I think i have fixed the problem now. I think i might have some issues with the harness plug/connection located passenger side under truck just behind right front wheel! I disconnected it and gave it a very thorough cleaning with MAF cleaner inside and out (of course after i had the entire harness down and checked from back to front :fu:)
Now my tail lights are working again, and truck can go WOT with lights on all the way to redline without problems.
So i guess if anyone have the issue with truck that are stuck in limp mode when lights are turned on, you might wanna consider checking this connection also!!

Cheers.. :cheers:
