My next project after brakes is the "wiry joe" that i have. It says primary and ignition. complete lighting circuit. the problem i have is it is pretty old and all the colors have faded into one color of yellow. the wire looks good, not brittle, and it has all the nice factory ends. I folded it out today and it looks fairly simple. identified the headlite circuit,, loom to dash and line to rear. i plan to hook up a meter and test all the wires to see who go's where. i'll buy some colored magic markers and code the ends. Question: can i pull the instrument panel out with wires still connected? how is it held in place? i am hoping to work thru that hole instead of lying on the floor...
ANother question: the harness has some connector ends, looks like half a fuse connector, can i buy the other half somewhere? what was fused? i dont see any under the dash now, there is a lot of "added" wiring...
Tim 37, did you have the same harness? the one you spoke of before the generator thread?
thanks
steven

With the few and simple wiring I would say that it would be the least amount of work to leave the dash and instruments in place.If I remember correctly the fuse on a 1938 is behind the ammeter and the only connector that you describe is for the horn-and it is under the hood near the steering column.

thanks gene,I saw the one connector maybe going to the horn, but there are at least two more. i will check tomorrow. i intended to just pull the instrument panel, not the whole dash. ,thought that would be fairly easy but could not see yet how it is fastened. that would put all those connections in my lap and i could reach thru the hole for the switch connections. dont much like working over head on my back if i dont have too. i am sure i will end up under there a bunch, have to replace defrost hoses and probably pull the wiper motor for clean and lube.

It will still be more under-dash work removing the instrument cluster from behind the dash than installing the harness

Steven - You only gain access to 4 connections by pulling the instrument cluster ( gas gage and ammeter). I rewired my '40 and rather the pull the instrument cluster I pulled the headlight switch and the ignition switch which you should do even if you pull the instrument cluster. That leaves only the ammeter and gas gage connections under the dash. The headlight switch is easy to connect once removed. Ignition switch is a little more touchy but the harness should have enough slack that you can pull the wires through the hole and connect them. There are 4 bolts that hold the instrument cluster in the dash. the bolts are pan headed carriage bolts with the heads held in slots in the main part of the dash. Do not completely remove the nuts but just loosen them enough that you can slide the upper bolts up out of the slots and the lower ones down out of the slots. Sometimes they are easy to work with but most of the time they are a real b---h. And, yes you can pull the instrument cluster with all wires and speedometer cable attached. Just be careful that you don't crimp the temp gage line. Good luck which ever way you decide to go.

Well i went under the dash today and i have to agree with what has been said about not pulling the instrument cluster. i am getting wires sorted out on the harness but the shop manual i have does not list any colors. the 41 shop manula that was just posted on line has the colors and a better diagram, but i cant make out the colors. it doesnt look to complicated, can anyone enlighten me on the colors. it looks like:
1. natural
2.natural with black tracer
3.natural with black crossed tracer
4. natural with red tracer
5.atural with red crossed tracer
6.natural with green tracer
have i missed any. if that is all maybe i can study the loom and pick them out, the crossed black i can see pretty well, and i thought i saw some red...
just need to know if i am on the right track. also do y'all think the 41 is the same as the 38
darned if the two connectors i spoke of arent on the ends of the taillite wires. dont know why they are there, i dont have any connectors, suppose mine got cut off at some time. tim says connectors are available in some of the cats.

i've traced and identified all the wires. i numbered them and attached gummy labels to each end with corresponding number. i'd still like to color them but dont know correct colors. i had a regulator question so started a new topic on that. thanks tim for the connector site. those are the ones. will have to order some. will make a much nicer job. anybody knowsthe colrs i'd sure appreciate it. there are only 13 different circuits in the loom and some colors must duplicate so one should be able to code them with the right color markers...

My 1939 manual does not list colors either.I wouldn't trust the 1941 colors as the 1941 had so many changes.
The wiry Joe harness is somewhat "universal" when it gets back to the tail lights.The connectors for the tail lights are usually in the trunk area-at least thats where they are on my '39.

that would be a good place for them! out of the weather.
thinking about colors some more i guess the wiring is so simple that once it's on in the right place and working there is no need for the colors anymore. now to just get it on...

What looks like half of a fuse is actually a bayonet connector. It's used on horn at steering column, two at taillight and a two triple conductor connectors at headlights.
Good luck!

Steven - I checked the '41 colors against my '40 colors and the colors are identical. Also took a brief look at the '48 manual and the colors are consistent. I have a wire list by color if you want it. I'm at deluxe1940@aol.com. Send me your e-address and I'll send it to you.
