DRL installation in steering column
Posted: Fri Apr 18, 2008 9:33 am
I'm in the process of installing a the Canadian Tire Hamsar DRL module (45040) in my Delica. I've got a plan for how to do it, I'd just like to run it past you all so that I can get a last minute "no don't do that" if I'm approaching this wrong!
If it works, then I'll try to take some photos and write it up for the Delica wiki, I've noticed this question comes up often. Please bear with me as I'm a total beginner with vehicle work!
This is the plan so far:
I've found two wiring harnesses coming out of the steering column: one for the ignition switch, and one for the headlight/wiper/horn/etc. In the ignition harness, I have isolated the 12V unswitched battery connection and the 12V 'on' switched power. These are 2 of the 6 leads that the Hamsar needs.
In the other harness, I expect to find outgoing leads to the low, high, and parking lights, which are connected to 12V by various states of the headlight switches. I will test these by moving the headlight switches around and looking for +12V on my multimeter, to figure out which wires in the outgoing harness. Once I have these, I'll have another 3 of the 6 Hamsar wires. The remaining wire is ground.
So the final wire layout for the hamsar DRL is this:
Green: 12V switched 'on' (ignition harness)
White: outgoing low beam lead (steering wheel controls harness)
Orange: outgoing high beam lead (steering wheel controls harness)
Red: 12V unswitched from battery (ignition harness)
Black: ground chassis screw next to fusebox
Yellow: outgoing parking lights lead (steering wheel controls harness)
I plan to use tap splice connectors to the wires that are on the non-steering column-side of the harness connection. In other words, just up from the harness, but not in the steering column bundle itself.
I'll mount the DRL box just below or to the left of the fusebox by drilling a couple of holes in the firewall.
How does this all sound? I think I can get all of the DRL connections within a few inches of each other this way. I want to get it finished tonight so if I'm doing anything stupid please tell me now :)
Thanks,
David
