Ok so i ordered 2 whalen vertex hideaways. They are installed in tailights and i have the wires ran up front. Now the question is they say to fuse the power at 3a and scan at 1a. I will be stopping at the store tomorrow to grab the supplies.
What gauge wire should i get?
Should i run fuses on the power and if so what should i get?
How should i wire up the pattern button? to another switch?
Something small like 16-18 ga wire would be fine. Always use a fuse and make sure it's as close as possible to the power source. This way, if there's ever a short, it'll blow rather than burn It says to get a 3 amp fuse, so just use that.
Pick up power from the 12v plug. If you don't want to go to the battery. If the requirement to change pattern on the go is not a requirement to you just run the pattern wire to the dash set the pattern and tape the wire off. Otherwise just put a push button
