OT: Daytime Running Lights Installation Problem

[Rod in Smiths Falls, ON]

I'm trying to install a Hamstar 45040 DRL module on my 2002 Tacoma to meet Canadian import requirements. The installation makes sense except that the green wire is supposed to "wrap around a spark plug wire" to gain power by impedence to signal the relay that the truck is running.

An alternative is to hook the wire to the oil pressure sender, but I'd need to be an asbestos octopus with a GPS to find that baby. (The wire's a yellow-green, according to the 2003 wiring manual.)

I've never seen an ignition coil mounted on top of a spark plug before. Of the four wires that run into it, is there one I can safely use to harvest a bit of impedence?

Alternatives?

Thanks,

Contact Hamsar directly and present your problem of finding a suitable source of inductance to trigger the DRL actuator on your particular vehicle.

Hamsar responded:

Hi Rod

The green wire needs to be connected to a source that receives 12V on
start up. This is to engage the DRL. It does not 'have' to be the
spark plug.

Hope this helps.

Thanks for you inquiry.

Thanks for the suggestion.

Good enough. I read your letter to Hamasar and your fix to connect to the oil sending wire. Hamsar makes a lot of stuff I never knew existed. What would we do without all the automotive suppliers.
