Ke wiring for various gauges

[johnnyboy_84]

Hey there, wired up a aftermarket taco in dash where my clock used to be but I seem to have an issue. Gauge works well and lights up when lights turn on, but when wipers put on gauge lights cut in and out. Do you guys think I might have spliced into a wrong wire or maybe just have a poor earth problem somewhere? Have other gauges to put in too but want light problem rectified first. Hopefully someone can help. Have a manual with light wiring diagram but doesn't really help that much.

you probably wired it to the power for the wipers so that when the wipers are on, there isnt enough power for your gauge lights as your wiper motors are drawing too much current.

Try a different 12v source

Good point. I'll have another look. Cheers.
