When I got my truck the cig lighter was rigged with a spliced wire that ran to the fuse panel and just connected by the end stripped back and pressed under one side of the Aux fuse.

It worked but I cut it away with the intention of hooking it up right. Well, for the life of me I cannot locate the blue/red stripe wire like the one on the cig pigtail.

So, I was going to connect it like it was, only go to the cig fuse on the bottom left of the fuse box. The fuse was a short stubby one, 15amps 3.2v. The fuse is shorter thatn the space it's plugged into....it looks like a regular size fuse would fit in there.

Anyway, I hooked it up, went to check the cig lighter with a test light....saw a spark and fuse blew.

Was the short fuse the wrong one? Can I hook up the lighter like this? If so, what amperage and voltage should the fuse be? 15a/12v

 

Wrong fuse....if you are reading it correctly.....It should be a 15Amp - 12 VOLT

I'll bet someone used the 3.2v one for power to an XM radio!

 

hmmm...I knew the truck was a 12v system, but I wasn't sure if all the circuits used 12v fuses with the rated amps. So then, ALL the fuses should be 12volt? The heater fuse would be 35a/12v? Is that correct?

 

You are correct!

 

The cigarette lighter power isn't blue with a red stripe; that should be dash illumination.
