Well i am rewiring the whole car. All brand new wires and harnesses from M&H - minus the body harness ribbon cable. $$$ I don't have to be spending, but oh well :-(

I ran into a snag. They need to know if my ignition system works with the points style wires or if it needs a keyed 12 volt source.

My details:
Mallory Promaster Coil #28720 Not the VoltMaster
http://go.mrgasket.com/pdf/28675_28720.pdf

MSD Pro Billet (Ready To Run) Distributor # 8360
http://www.msdignition.com/pdf/8360_frm%2023793.pdf

I tried calling Mallory, but I was on hold for 20 minutes and then got disconnected.

Thanks

That is an electronic distributor so it needs full 12V power.

The points distributors required a resistance wire to reduce operating voltage (and used a second regular wire for full voltage during starting).

You want HEI style wiring.

Vrooom, much appreciated for the quick response. now I can find out how much this will be and how long till I can get it. Crosses fingers that it will be soon and I can go and pick it up instead of having it shipped.

While I have your attention, this brings up something that confused me...

So I have electronic ignition then. And I DO NOT have points with that Distributor.

Well, when I looked at the description of my coil, I noticed that it says for use with points distributors. Is my coil and distributor mismatched?

Jim. What it means is, For use with "points type" distributors. As apposed to HEI. You have a points type dist. It just has a "electric module" instead of points and condenser.

The Promaster coil works with either, according to instructions you posted. I have used the Ready to Run with both stock and Pertronix coils. It comes with good instructions and the wire loom. Nice piece.

Ok thanks.

They will also mod the harness for a internally regulated alternator. You might also want to ask if they add fusible links. 65's didn't have any and adding them would be a good idea.

Already did the order. They called this morning and said it was ready to pick up. I guess I will just add the fuseable links myself as to not have to wait 4 weeks for custom work.

Is this something I would be able to do?

Yes, if you are picking up, just ask while you are there. The main fusible link is between the battery and junction block and is really not part of the main harness. The other is on the horn relay. They also sell a conversion kit to make a original harness work with a internally regulated alternator.

Oh yeah, here is what I ended up getting:
Fwd Lamp w/ SI int Alt passenger side - 39054
Engine HEI - 38953
Dash - 05960
Courtesy Harness Dash Light - 07580
Glove Box Light - 18000
Ground Strap - unknown
Wiper Motor Harness (single speed) - 28415
1/3" vinal tape - R0058272
Assembly Manual - 36295
Windsield Wiper Switch (single speed w/ washer) - 01993680

Did not get the following.
Rear Lamp - out of stock for 4 weeks
Console - out of stock for 4 weeks
Body Harness (flat ribbon) - not sold by M&H

Now on a few of the diagrams I have seen a junction block. But on my car, the only junction block I have is the horn relay.

Also, just called M&H, my rep didn't know what I was talking about with the fuseable link. I don't want to make waves over there, so I guess I will just wire my car up with what they give me, and add one later on.

Also, just called M&H, my rep didn't know what I was talking about with the fuseable link. If he/she didn't know what a fusible link was, then that person was probably just a order taker. You can get one at autozone and add it yourself.

Ok will do. I will hit autozone on the way back while I still have a ride. What should I pick up, and where/how do I put it on?

Thanks for all the info.

I use a 14g fusible link for a FORD. It already has the ring terminal one one end, (fits the original junction block) the GM ones don't. You also have to add a short piece of 10g wire to it and another ring terminal to fit the battery. Be sure to crimp and solder the two together as this is a main connection.

So then the large battery cable still runs to the starter.

Then take the 14g fuseable link and connect it from the horn relay all the way to the battery?

The fusible link originally went between the battery and junction block (junction bloc is just a plastic connection point). Fusible links are only 4-6in in length. See pic

Yeah, i don't have a junction block.

You can either buy a junction block or just connect the wires together without one. If without, be sure to insulate the connection well.

This is what the junction blocks look like:

American Autowire carries them and I would be surprised if M&H does not. The standard harness will likely have a wire built in to go across the top of the core support and bolt up to the junction block. Then you are expected to provide the wire from the junction block to the battery.

Personally I am not a fan of fuse links and prefer fuses. American Autowire has a couple that would serve well as junction blocks and master fuses. Check out the bottom of this page and look at the MEGA and MIDI Fuse assembly kits:

Failing that on a more local level, a lot of the high power stereo amplifier setups are running their own very large power supply wires. Thus they have large amperage fuse holders that could be used in this application too.

Just to re-iterate a point here though: these joints can carry a lot of current and thus are very sensitive to connection quality. The effects of any loose connections or oxidation or dirt will be much more detrimental than usual. Soldering of terminals is very highly recommended.

One lead for your amp gauge will connect to the J-block, the other to the horn relay, so it will be better to get one (j-block). Hate to make this more complicated, the amp gauge wires also don't have fusible links that were added to the same circuit in 67.

Well it took me four hours to pick them up. left at around noon and just got back. Thanks go to the President making a trip out here. but I got the wiring harnesses from M&H. then I went to OPG and picked up a rear lamp and console harness.

I also picked up a junction block from OPG as well for 5 bux.

Oh and a Assembly manual. i plan to study that tonight at work. Unfortunately I can't start working on it till tommorow.

Here's a pic of my goodies:

Grand total for all was $996.09 :(

Hey data, if you went from Hollywood to Santa Fe Springs and then OC, how did Bush's trip stack you up? You shouldn't have had to go to the westside at all. It's the lousy I-5 you need to blame, unless you took the 405 back from OC. Anyway, four hours ain't all that bad for that trip!

You are about to turn the corner on this car, so take heart.

I had to borrow a friends truck that works in Westwood. Trust me, I was there. Marine One and his decoy flew right over my head when I was by the VA. It was kinda cool. ha it took me over an hour to get from the 405 exit on Wilshire to Sawtelle. So rediculous.

Anyways, I hope you are right. Just with all the time spent on this car and what I have uncovered... I am fearful that when I get the electrical dialed in and reinstalled and the timing where it needs to be... I am going to find something else in need of a major overhaul.

I hate to do this... :)

Be afraid, be very afraid!!!

It will quite likely happen, at least for awhile. That is why my El Camino has a new motor, and new axles/bearings, and seals in the tranny, and and and... ;)
