Headlight relay upgrade

[annularnos]

I think John and I have figured out the 71 switching situation, a relay solution for 71 cars is done.   I asked John to get some pictures of road lamp light plug inside your housings.   I assume, I know dangerous, that 1970 use the same internal attaching plug.   Once I know that plug, I can get a road lamp kit together using larger sized wire. 

On a 1970, being a single headlight per side, I believe that you can run your road lamps with the car on high beam setting.  Is that correct?  There is no switching off of your road lamp when you go to high beams?   I think that is a fed regulation about not having more than 4 forward light illuminated at any time.  71's have to switch off the road lamps, otherwise they have 6 lights.

If you have any pictures of your lamps taken apart and the internal connectors, I'd love to have them for reference.  John's as well.

Please let me know the answers and any pictures and we can get a solution for 70 & 71 road lamp cars.

Performance for all the lights should increase dramatically.

Rob-

I've been out of town working and got back home today. I'll hopefully have the road lamp socket info for you tomorrow.

No problem John.  Work takes priority.

I did find these on another site which appear to be the replacement number, 4415, for the OE roadlamps.



If the connectors are like these, that's a piece of cake to work with.  A couple of ring terminals and we are good to go.

I need someone to come in a do some just-in-time inventory control processes.  I have a bunch of buyers and keep running low on different colored wire.  I guess that's a good thing.   

I should have enough wire on the rack to do about 30 cars on Monday.  Then I run low on relays... it never ends!

I did the relay thing a few years back on my '88 suburban. Used the MAD Electrical diagram and some relays bought off ebay and high heat lamp sockets, made my own harness out of 12 ga. wire.
WOW! Night and DAY difference!
Just like Tommys pox shows, my low beams are now as bright as my high beams once were.
Good work!

Installed my headlight relay kit from Rob.
Worked great once I hooked the ground that I forgot... Hiding the wires I hid the drivers side ground before connecting it... oops.
Thanks for your help Rob.

Mounting the relays under the battery tray.


Battery tray re-installed


Drivers side wire routing.


Routing across for passenger side and hot wires to alternator. Not totally hidden but they are tucked up out of the way pretty well.




Red and Gray Hot wires connected to the alternator. You can see the black #8AWG wire from the Alternator I ran to bypass the bulkhead.

Randy,

No prob on the tech support, part of the purchase.  I want people that buy from me to be happy with the product and know that if they have a question, I'm a PM, phone call or e-mail away.   Last thing I want to do is leave customers feeling as though they are hanging in the wind.

Install looks good.   Love the car, nothing beats a nice vert cruise on a sunny day!

WOW this is very interesting!  So how hard is this to install for someone like me that doesn't know alot about the electrical system of the car.  I can honestly say that is my weakness when it comes to these cars . . . . also how much is the kit for a 70?   Will it work for a 73 as well?

I am interested in knowing this as well. I can send an email if you would rather not post a price in public.

Very easy to install.
Hook up two power wires, 3 grounds, headlight plugs and a trigger wire plug.   Not difficult to install a kit.

A kit for a 2 headlight car is 130 + shipping.  4 Headlight cars are 150 + shipping.

A 70 Cuda kit would be virtually indentical to a 73 Cuda kit.  Both being single headlight cars.

I have instructions that were done using some Darts/Dusters, same basic principle for an E body car.

If I can do it, you can do it.

Also where are you located and do you take paypal?

Ragtop, did you run your alternator wires over/under the rad support bar? Mine run across the firewall and over the passenger side valve cover. I guess anyway that makes it cleaner for you, but I guess another option would be to run it right across the top front of the motor (which is where I ran my 8g starter relay bypass). That would definitely be the shortest route.

Tommy,
Since I had already ran the #8AWG wire from the Alternator to the starter relay via the passenger valve cover-firewall path, I didn't want to run the HL alternator wires that way too. Thought it was getting a little crowded.... I also thought about shortening them and just connecting to the starter relay. The #8 wire is plenty for the current of all the accessories but decided to route them together with the passenger side HL leads zip tied to the factory harness on the front top of the rad support to keep it a little cleaner. I like that they are home ran to the alternator too.
The alternator wires are long enough to go down on the front side of the rad support and come up with the washer wire and hose and then followed the horn wires to the alternator with just a small loop of excess I coiled in front of the rad support.
You really don't see these unless you're 3 feet tall or on your knees...


The thicker HL alternator wires zip tied to the bottom of the horn and washer wires.
You can see the fat black #8 wire dwarfs the original tiny black alternator wire and loops back and follows the stock harness to the valve cover.

Annularnos,

Here's a pic of the kit on it's way to you.



This kit has High/Low and road lamp provisions.

Thanks for the assistance and  purchase.  Please let me know if you need anything.

I'm in the Palm Springs area of California and payapl is an accepted form of payment.

Thanks.
