[74Manta]

So I've finally got my manta, and I'm trying to work out all the bugs so I can get it registered and inspected, but I can only get the two outside lights to work. They work on both high and low beams but the two inner lights never come on. Is this a wiring problem or a relay problem. If it is a relay problem can someone tell me where the headlight relay is because I can't find it under the dash. Thanks

As far as I know, they work off from each other. But I have not had a problem with Manta wiring myself.

I do konw that there is a wiring diagram floating around the internet somewhere that would help a lot. All I can offer is this photo of mine.

74 Manta relay

I have the problem described in the first post, and it seems that the 74 Manta uses a high-beam relay to activate the inner (high-beam only) bulbs.

Anyone know where to get one of these relays? It's a 4 pin with a non-standard pin configuration.

the relay is a standard 4 prong relay that is commonly used on driving lights

Pin wiring?

The relay that I pulled out (Hella 4RA 02 556-03) has pins 85 and 86 next to each other. The NAPA part shows them across from each other.

I don't think that will work but then, I'm no electrical wizard.

I had a similar situation with my wife's Sentra, relay socket for fog lights had 'unconventional' configuration. (The correct relay from Nissan was $60+, the relay I used from NAPA was about $7.00, just different pinout.)
I made up 4 jumpers, about 1.5 inches of wire, 4 spade terminals and 4 spade connectors, one terminal and one connector per wire. I then just plugged the spade terminals into the connector socket, noted which was what number, and the connector end onto the respective spade terminal of the relay.
Been working great for more than 2 years with no problems..

did you ever solve this? And if yes any chance you recall (11 years later) if this worked? I have the exact same problem

Yes, I solved it.
No, I don't recall how.
Yes, I'm old!

Try taking the relay to your local auto store and see if they can match it up. Otherwise, the jumper setup that Larry T posted above should work.

Good luck!
