"Need Help with Relay"

[smoke'sDat's]

Good Morning guys, for the past several months I've been working on a "wire tuck" and some other interior projects on my Datsun 620 truck. Now that I'm almost finally done, one thing is holding back. I need help re-wiring this relay. Honestly I don't remember where they are connected because it was a total nightmare with the wire tuck. Can someone tell me where the yellow, white, red and black wires are connected to. My truck has been on jack stands for almost a year and a half and I'm really anxious to get in off the stands and on the road cuz I miss driving it. So, can I get help with this relay please !!!!!!

Looks kind of home made.

 

Seldom are solid color wires used. Usually they are a mixture of striped.

 

Is this the normal location for the relay?

 

What year 620, and where is this located?

I honestly don't know if it's home made. It's been there ever since I purchased my truck approximately 6 years ago. The relay has been on the passenger side underneath the a/c cooling unit by itself and I know that it wasn't connected to the unit. From what I remember the yellow wire was connected to the + positive, the white wire to the ignition switch and the red I think the my aftermarket radio. That's why I know that its not normal place for the relay. I have a 1978 Datsun 620.

Normally I don't think there are any relays under there on the 620. I had a '78 but no a/c. All the relays are on the inner pass side fender I think.
