1978 280z underhood relays

[az240z]

I am rebuilding a 1978 280z that was stripped many years ago. At the moment I'm trying to get the relay shelf and relays together. I think the 78 280z uses 4 relays for a 5 spd manual:

1. A/C relay 25230-4205 4 pin connector

2. EFI main 25230-89970 4 pin connector

3. fuel pump control 25230-8996 5 pin connector

4. Fuel pump 25230-H7200 4 pin connector

The picture shows the relays. I don't beleive I need the inhibitor because of the manual tranny. The question I have is, in looking at my old relays 3 look alike. 2 are marked 25230-H7200 while they other can't be read. Does anyone know if these relays can be used for all the 4 pin connectors??

If not anyone know where I can get them? Would like to install new if possible.

I believe the 4-pin fuel pump and A/C relays are indeed interchangeable. I assume the inhibitor relay is interchangeable too, although I don't have direct experience with it.

I am tearing down a 78Z this week. It was a whole running car with front end damage that was too expensive to fix. I had the car since 94 so I know everything about it. The car is going to be rebodied as a GT250 now. So all the parts are available. It has a brand new lockset with one key for all locks and ignition, euro tailights, real nice center console, nice fractory original style carpet kit, F54 block with N47 head, new fuel injectors, nice door panels with a custom door speaker panel. Only bad parts are the hood and right fender. The car has MSA side skirts and front valance. I even have nice hood vents including brand new ones. So in the end I got lots of parts for a 78 in San Diego.

what about the wiring harness??

I think they use it for the GT250 kit.
