Hello Folks,

I bought his 88 Canadian Doublecab some time ago. I'm now in the midst of
trying to figure out why the dash lights don't work. I've already eliminated
the bulbs as I tested them individually. Not only that, I put a completely
different cluster which worked fine in another van. The headlight switch has
been replaced as well with a known good one.

Herein came the problem. I saw that the previous owner wired the radio to
the ignition switch wire. Now the radio powers on or off when the key is
removed. Doesn't seem smart since that makes the radio presets go out when
no "on all the time" power is provided. That's not really the issue but I am
concerned that it might be affecting my dash lights. What most concerns me
is trio of wires which were taped together. One wire is obviously Brown for
ground. Another wire is Blue/Grey. The third is Black/Yellow.

Does anybody know what these wires are for? I'm wiring diagram challenged.

For that matter, can someone tell me where the dash light power comes from?

TIA,

BenT
