dash lights wiring diagram

[speed1972]

I've been hunting down wiring gremlins in my dash lights this weekend and I've come a long way to say the least. I have no power to any dash lights.... I've got power from the headlight switch to the dimmer switch. I've tested the dimmer switch and I have good power there... So replacing the dimmer switch isn't the problem. I can feed power to the old radio wire and all my dash lights will work. Is there a fusible link somewhere in harness? Where is it and does anyone have a diagram that shows the dash wiring? Already looked at the autozone diagrams and nothing covers dash lights that I saw. If all else fails I'll run a new wire over to the radio wire from the dimmer switch. Thanks in advance!!

fuse 13 is the ISO, aka dimmer fuse. either a 3 or 5 amper, i cant remember.

good luck.

I know which fuse it is...(thanks for the info tho) but I need to find out where the wiring goes from the dimmer switch out. Does it go through the fuse block before or after the dimmer switch?

fuse 4 to light switch to dimmer to fuse 13 to pins 11 & 13 on IP connectors c250 & c251. wires are LB/R.

Cool this is definitely what I was looking for...one little question though, what are the IP connectors c250 & c251?

thank you much, Larry

 

[JB66]

Instrument Panel connector c250 is a gray 14 pin
c251 is a brown 14 pin
Both go to the instrument panel.

thanks for the info JB, I got it figured out now and have working lights again..yeah

nice info JB.

Speed, what was the cause?

It ended up being a wire shorted out down by the radio. I sealed the open wire and replaced the fuses and haven't had a problem since.

nice work finding it. seems to be a common issue. if you see a thread by Killerrobot maybe fill him in on the wire color for the illumination wire. i had posted that it was (per my vague memory) orange or orange/white, but i reallized that is probably the color on my harness adapter. if he does not have those, i dont know what the oem color is for the illumination wire.

BTW, what happened here. are we starting over (i.e. all old threads were lost)? no page 2. LOL.

 

[HISSIN50]

oh yeah, i lost ~2500 posts.

 

[speed1972]

what happened to cause you to lose all those?

SN crashed earlier.

I see that now... Maybe they should have backed it up more frequently
