I just bought a new to me 04 Taco and some of the dash bulbs weren't working so I pulled the dash (thanks to a lot of great how-to's), I'm going to go the LED route.
Since LED bulbs are polarity specific I'm having a hard time figuring out which side of the connections are Positive and which is the ground. I've searched hard (probably not hard enough ) but can't find a wiring diagram for the gauge cluster.
Yeah, I know, plug them in and test'em then reverse if needed but I'm replacing all of the bulbs with LED's I really don't want to install the dash just to test and then remove it again to correct. Also, I'm not 100% sure how to test all of the bulbs. Problem is I think I need to connect all switches which currently aren't connected since pulling all of the panels. The one panel that covers the gauge cluster (which has the switches on it) is a pain to remove/replace.
Sorry for the long post, but does anyone have a wiring diagram for an 04 Tacoma gauge cluster?
