Electrical Questions?
I'm using the ARB CKMTA12 for onboard air (ordered through Chris at UJOR) and I need to run the provided wiring loom to the dash. To wire up the switch, I need to locate the positive wire of an accessory outlet and active dash light supply wire - I assume I can find that running to my dash light dimmer switch left of the steering wheel. I'm kind of new to all things electrical and really want to tackle as many of these little projects as I can to learn more. Google + is where I've always been storing my pictures and suddenly they are all posting much bigger than they were before and I can't find out how to resize at the moment. Sorry for the inconvenience.
Any suggestions?
Here are some pictures with other questions too:
I need to bring the switch end of the loom in to the cab through the firewall - I'd think it would be safe to drill out this dimple that's already there, correct? Or do you guys try to fish things in along with other wires already present?
View from under the hood:
I assume this is the same dimple on the inside in the back of the footwell:
Random button attached to the brown wires coiled around a wiring harness behind the panel below the steering wheel...not sure what it could be?
I assume this is a plug and play port for a 3rd party trailer brake controller because I have a 2010 V10 E350 with trailer tow package and the auxiliary battery. Upper right of picture - gray in color.
I wanted to put the switch on the gray panel below where the alarm system indicator light is, but this big styrofoam block is in the way...should I remove that? Or should I put the switch near the dash dimming switch? I think there is room but when I eventually get a rear air locker I'll have to put that switch somewhere close by and there doesn't seem to be room for two there.
Thanks for any help you can provide!
