68 Charger starter relay

[terrible one]

I'm wondering if anyone can help me out with wiring up my starter relay. All I've got going to the location so far is the positive battery cable and the fusible link coming from the bulkhead. I'm sure these all go to the two studs in some fashion but what about the tabs, marked I (ignition?) and G (ground?)

Also, I don't have the headlight wiring or wiper motor/ wiring (hence the two empty slots on the bulkhead) . . . will that keep me from starting the car?

Here's a picture:

Hi,

I can help you along the way but not all the way as I'm not 100 %.

The (I) is going to the Ignition. Should be a yellow wire that is hooked up to the 'T' terminal on the bulkhead (on the headlight wiring, upper row, second on the right)
The (G) ground is hooked up the neutral safety switch, just hook it to a ground somewhere to start the car.

The battery cable and the fusible link all go to the big stud.

The one I'm not sure about is the smaller cable in your hand. ( I don't have my car here so I can't look for you)

Hope it helps!

Here's how it's hooked up, in your case the blue fusible link would go to the large threaded stud in place of the red in the pic.

Thanks for the help guys  

So, the yellow wire that goes to the "I" comes from the ignition switch through the headlight wiring harness part of the bulkhead. I guess that means I need to go ahead and order the headlight harness then if I want to be able to do this right, huh?

The smaller gray wire you were asking about Per is spliced in with the other part of the positive battery cable that goes down to the starter and connects to the smaller terminal, so that goes on the "to starter" bolt in the diagram.

I think I've got it figured out then. Hooked it up like below. I just hate that the yellow IGN wire comes from the headlight harness . . . one expensive thing I don't have yet.



The "G" / neutral safety switch wire is a whole 'nother story. The trans I am using is a 727 from RD that came with the 3 prong neutral safety switch, but the car is a '68 with the backup switch on the shifter, so I don't even know what I need to do for that.   Any ideas?

The switch on the shifter is for backup lights. I have my interlock wire run to the grounded screw that holds the relay (Just do not start the car in any gear or it will crank over) until I get the right harness for my 727.

In order of "goodness" 1) Get a '68 switch for the trans 2) modify your harness to only use two of the 3 prongs 3) or get a '69 trans harness and modify your '68 body harness with butt connector instead of shifter switch and use both features of your dual function trans switch.

Thanks again for the help everyone. So obviously just for starting I can ground the NSS terminal on the relay as long as I make sure trans isn't in gear like b5blue said.

Still, I will eventually need to get things wired up right with the backup lights and NSS. . .

I would definitely go with the '68 switch except during my searches before posting I found reference to the levers inside the transmissions being different for each switch. I have no doubt that RD matched up the 3 prong NSS with the correct internal lever so I'd say I'm pretty well stuck with the 3 prong setup at the transmission.

That said, I don't have any type of wiring harness coming from the transmission right now. Also, although I have the '68 shifter mechanism the switch that would be mounted on the shifter itself (that the two purple wires go to) is no longer there. Basically, I'm starting with nothing in this area.

So what would be my best option in that case? Basically I'm starting from scratch though I do have all of the '68 console wiring (just not the backup switch on the shifter). I wouldn't mind using a '69 harness or making a harness or whatever I needed to do, but as you can tell I have no clue at all when it comes to electrical. I just want the most economical solution. What about using the '69 harness (made for the 3 prong NSS) and just ignoring the backup switch on the shifter? Would I still have to modify my new harness to make it work?

[b5blue]

The way the dash is harnessed I believe you need the switch on the sifter for backup lights, (Easier and cheaper to do right) the tranny switch just supply's ground in park or neutral. 

[terrible one]

I think you are right.

So, in that case I plan to do this:

Get the 68 backup switch and connect it like stock, then just run a wire from one of the prongs on the nss (does it matter which?) to the "G" terminal on the starter relay.

Sound good?

[b5blue]

Yea! Just find the one that is "grounded" in "park". 

[terrible one]

Cool! Thanks!

[b5blue]

Good Luck!

and N

[b5blue]

   Yes, I think he is hoping to just get one if he can!

[terrible one]

Haha yes really NEUTRAL is quite important because I want to start the car in N so the trans is pumping fluid. 

Nacho, do you by chance know which prong on the 3 prong NSS is ground or will any prong work?

[Nacho-RT74]

outers are reverse light switch... one of its wires is HOT when key in RUN/ACC, center is P/N ground

[terrible one]

Thank you for that

I have no doubt that RD matched up the 3 prong NSS with the correct internal lever so I'd say I'm pretty well stuck with the 3 prong setup at the transmission.

The correct '64-'68 single prong NSS will work with the 3-prong internal lever.

That is great to know! In that case I can eventually go to the stock setup pretty easy. I did a bit of searching and it looks like the single prong switches aren't reproduced though so I guess it's a good thing I can make the three prong work for now. Thanks John

just in case... pricey, but:

Well that's definitely not so bad compared to some of the other prices I've seen! I saw some that were close to $100. I wonder if the ones in that auction are NOS or if someone is remaking them? Either way I will definitely wait until some other "higher priority" parts get taken care of first though
