I installed aftermarket led taillights and had to cut and splice one wiring harness now my tpms gauge blinks and is blank, my high beam indicator doesn't work and my green turn signal bulbs don't work on steering column. I took it to nissan they charged me 200 fixed nothing and told me they would have to rip apart my dash and test all voltages with no time estimation nor cost estimation. All of this sounds so severe and not needed please help i would be so appreciative u r the only people i can trust thank you for any help.

 

Dude there's roughly 1 kagillion threads regarding issues with led tails and the problems they cause.

Search and destroy, good luck....

 

Undo what you did and see if the old lights work again. If they do, then your changes were wrong. If they don't work, then you've screwed up either the harness or the BCM (body control module- $$$$)

 

Did you disconnect the battery before working on the wires?

WHen I was messing around hardwiring my excort I blew a fuse which caused those lights to go out on my dash.

I just identified the fuse and replaced with one of the spare fuses.

So check the fusebox by your feet in the driverside.
