Delica Canada | Mitsubishi Van Club

Ah, the joys of used car ownership!

I've discovered a couple of wires under my floor mats that obviously weren't part of the Master Plan.

There's a red wire that runs form the battery terminal to the windshield wiper harness. My guess is if I disconnect it, the wiper motor won't go. Probably a previous owner got fed up trying to fix it and improvised. But why does it go into a hole in the duct work? And why are there several holes drilled and unused? Is this related to the Rattle Under the Dash?
The other mystery wire is a blue wire, found under the driver's seat. It extends under the floor mat, where it's not connected to anything. It goes into the hatch behind the driver's seat, where it disappears into one of those black plastic cable shrouds. What's that wire shroud normally for? Where does it go? Does your Delica have one?
Any guesses?

Where you have a blue wire I have a couple of boxes that makes up the 'ECU' as far as an L300 is concerned...

You are correct in that those wires are not part of Mr Mitsubishi's master plan the wire going to windshield could be a replacment power feed to the park circuit on the winshield wiper, if thats whats happening it means the wiper switch relay has died which means you need a new wiper/headlight combo switch. The blue wire i don't know what its for or could be for. if its noting going any where pull it out i've pulled out tons of crappy wiring in Delis.Cheers Jay Tardis Deli

As it turns out, the red wire was someone's attempt to create Day Time Running Lamps. They picked off power from the wiper harness, and ran it to a relay behind the left headlight. Which got all corroded, and the wires fell out. Stupid arrangement, really. I yanked it all out, and the wipers work fine.

I think that blue wire is supposed to be connected to the parking brake so the light goes on when it is set
