Re: Color Wiring Diagram FINISHED
 

Okay, so I just went and looked at a different brand replacement. It matches the pinout I posted yesterday. What gives? Are these wiring diagrams wrong, or is there something I'm missing here about the replacement part. I know somebody out there has replaced their ignition switch harness. HELP :waah:

Re: Color Wiring Diagram FINISHED
 

Are you using part number PT298 the colors are not correct on your connector (the diagram is correct) but will still work below is a pic from BWD website for part number PT298 with the correct color code. Note the purple and brown wires.

Re: Color Wiring Diagram FINISHED
 

Yes, but... Here's the problem... The one on the left is the one from the diagram. The one on the right is the one I have. Also, the diagram does not actually show enough prongs for the connector. Even the factory connector has two prongs on the left.

Re: Color Wiring Diagram FINISHED
 

Okay, so the extra red wire is a way to wire something up that you want to always have power, in run, accy, off, and start. Such as??? Load limits?? Effects on the rest of the system?? The two purple wires on the diagram go on the SOL tab, second from left (the one you can't see on the diagram). The brown wires are correct (ACC). And the rest looks good. So, in other words, other than being a bit vague, the diagram IS correct. On a side note, nice work on the diagrams. If all that's true, then the wire that's missing goes to the "NFW Safety switch". Excuse my ignorance, but is that another way of saying Neutral Safety Switch (NSS)?? If that's the case, then awesome, because my truck never had one. Am I getting too far off topic here? I've been told I thread jacked already, so I'm trying to learn some online etiquette. Enough questions yet???

Re: Color Wiring Diagram FINISHED
 

I was looking here for this same issue, they are factory wires and are in the diagram. Any ideas what they actually do???

Re: Color Wiring Diagram FINISHED
 

Toejam, the bottom wire seems to be a double of the wire that has the fusible link on it from the battery. Look where the power wire splits into four wires. One of those wires is supposed to have a fusible link on it and doesn't. They go the same place. I think the wire on the top is the same deal. It's trying to show the two wires with fusible links on them, but instead of showing it on the proper wire, the wires have been duplicated.

Took a few pics today...

The fuse at the battery connection
Attachment 577504

and the alternator junction (yes, I'm modifying it to add elec. fans)
Attachment 577505

and the back of the fuse block
Attachment 577506

All I really want to know is what do they feed?????

Re: Color Wiring Diagram FINISHED
 

Those wires are for the factory ammeter

Re: Color Wiring Diagram FINISHED
 

fixit-p---Thank you! Thank you!:clap::clap:

never thought it would be that hard to figure out.

Just something that was driving me crazy. Not that that's hard to do.

Re: Color Wiring Diagram FINISHED
 

Yes, the two fuses are for the Ammeter so don't mess with them. Your diagram isn't complete all the way way to the dash or you would probably have found where they went. If one or both of the fuses burn out, the gauge will not work.

That is not the best place to pick up your 12 Volts. The red wire that goes from there back over to the battery is already serving as the Alternator charging wire and provides the shunt for the ammeter. It doesn't need you tying accessories onto it.
I would recommend replacing that single pin insulated junction next to the battery. That one is to small and probably ready to crumble into 40 year old dust. That is where you should tie in your new accessories, next to the battery.

A lot of guys replace the original insulated post with one from a S10 and that is very similar to what you will find in a flaps. If you have a lot of accessories you could use two S10 posts. One would hold the battery wire and all original wires. A jumper from there to a second S10 post that would hold all of the new accessories.

I found a small fuse box with a large post on the bottom to hold all of the original wires. The fuses feed the various accessories as well as some relays in the corner.

In case you were wondering the radiator over-flow bottle is from a '70s Nova.

Re: Color Wiring Diagram FINISHED
 

hey guys, can someone send me a hi-res copy of the wiring diagram? My email is twbailey75@yahoo.com Thanks in advance.

Re: Color Wiring Diagram FINISHED
 

I am trying to figure out what size fuses I need for my fuse panel. I looked at this diagram and if they are on here i am not seeing them.. if they are not can any of you please point me in the right direction.. I am unsure what sizes of fuses go were in the fuse panel. Thanks I have a 67 chevy c10

Re: Color Wiring Diagram FINISHED
 

Sorry if i missed it, but im looking for a digram for my straight six. is everything the same? If not can someone post it or send it to me tagar89@gmail.com

Re: Color Wiring Diagram FINISHED
 

Yeah im looking for the wiring for my straight six too. So if someone could tell me where on here i can find it or what?

thnx Twistted

Re: Color Wiring Diagram FINISHED
 

if u go to 4200x2250 and either save this diagram to a thumbdrive or your desktop u can blow it up and explore it and u wont have to ask someone to email it to you the link is at the top of the page

Re: Color Wiring Diagram FINISHED
 

thanks for the diagram . On yesterday i was cruising and a wire got caught up off of the hid kit i installed and riipped a factory wire from some where and when i went to diagnos the problem it was a nightmare. So thanks a ton for your hard work and dedication to the cause

Re: Color Wiring Diagram FINISHED
 

No, the links are not working. Do you still have this autoCAD document? It would be invaluable to me. I am making a few changes in different areas, and I think it would be great to be able to change the diagram around to match. Thanks in advance.

Re: Color Wiring Diagram FINISHED
 

I also have the pfs' and would love a copy of the cad version if they are still available.

Re: Color Wiring Diagram FINISHED
 

Man, that cad version must have taken some time! Hope it shows up here again so people can get more use from it.
