Dunno how similar 92 and 93 are, but I JUST got a brand spankin new EVTM on Saturday from Helm. It covers everything up to the F-350 for 92. Did 93's have the high brake light? I know 92 did not. I was thinkin that was added in 94, but I could be wrong.

Tim, I believe you're right...I think the third brake light wasn't introduced til 94......

Here ya go!

third brake light was not introduec until 1994.. 1994 is when Air Bagg, Third brake light and R134a was introduced into the trucks, also the start of the new firing order on the 5.0

Ok, what's a good website to look on for wiring diagrams. I got my license plate lights figured out.
So the next problem is my dash lights. Torn the dash apart last night, couldn't find anything, and all my gauges work. When I turn on the headlights, the dash lights don't come on. Guy I bought the truck from said that he had a mechanic look at it, and they couldn't find anything. ANy ideas? I checked the connections, bulbs, switches, fuses, and can't find anything.

You check the connector on the back of the light switch yet, or for that matter the switch itself? Common failure for a little corrosion to go a long way toward overheating a connection, and making it quit altogether. This normally causes extreme heating, and may damage the connector.

 

[DocWest8404]

yea, we checked the switch, looked good. Hit it with a test light and multi-meter. I'm starting to think it might be something in the wiring.

Doc, I've yet to find a website that hosts wiring diagrams for these trucks for free. My diagrams come from my 95 F-Series Ford shop manual (CD).

 

[DocWest8404]

Where can I order one for my truck?

 

[Skandocious]

Try eBay. I nabbed mine from FordCDs.com before FoMoCo sued their butts

 

[DocWest8404]

Kewl, see if I can find out later. Luckily I get paid tonight......

You can also find a few key electrical diagrams in a Haynes or Chiltons manual.

Stupid question but does your odometer work?

As much as I hate to say it...the Haynes manuals have better wiring schematics than Chilton...same company I know so wth?

yea, the odo works, which is wierd cause it's digital

 

[flareside_thunder]

Yea, I was asking because the interior lights,gauge lights and ODO are tied into the same fuse....
