FUN WITH ELECTRICITY
Today I took on wiring up the car for trailer lights. It’s a fairly simple job but I’m complicating it by not running power directly from the battery (I don’t want to snake a wire under the car). Instead I’m trying to wire into a 12v socket in the trunk. Without clearly marked wires or a voltmeter I got as far as I could today which was everything but power.
LATE NIGHT UPDATE
We have power! We’ll, we’ve had power all along, but… It turns out the trailer lights return to ground through their bolts and not the wires, I missed this and while testing the lights off of the trailer I had no such ground. Thanks to DrTune and his handy bag of tools we discovered the problem and came up with a grounding solution for testing purposes and I’m happy to report that the trailer lights work.
This is the power wire, backlit and over-exposed. Ooooh-Aahhhh.
Electricity hurts. Before I splice and twist all of these wires I cut the power at the battery.
NO JUNK IN THE TRUNK
I need a little room to work so everything in the trunk must go.
This handy box converts the signal my car passes (PMW) to the taillights to something I can pass to the trailer lights. I need to splice this into my left and right turn signals.
BRAKE LIGHT WIRES
Here are the three wires that control the driver’s side taillight. I’m going to splice into the yellow and black signal wire here.
Signal wire spliced (at the blue connector). The white wire is the ground.
I’m hoping to run the power through this plug into a 12v socket in the trunk. I need to borrow a voltmeter to work out the polarity of the wires on the plug. I’m using the plug because I’d rather not run a wire under the outside of the car to the battery, and since there is already a power source in the trunk…
