Another wiring query...

[Toed64]

Well, I'm very happy to say that, yesterday, my Exocet stated for the first time in my ownership ;D. It was quite a relief as it was an unknown quantity.

I've spent a fair bit of time removing bits of redundant loom, but as I didn't break the original 1989 Eunos, there are a few labeling oddities and absences. I spent ages trying to track down an indicator problem, only to discover that the flasher relay is U/S. Simple fix!

Can anyone tell me about the relays and plugs that plug into the loom on the right hand inner wing leg of the harness. There are a matching pair of relays, in rubber boots, mounted on a steel bracket. There are two plugs leading off the wiring, one is for a radiator fan (I think), the other was labelled 'oil cooler' by the guy who stripped the car - not really sure what he meant by this. There is also another small relay, 8 inches from the pair of relays, on this chunk of wiring. The whole lot plugs into the harness on a multi-plug, a couple of feet from where the alternator wiring splits off.

I think that this lot is probably all for the A/C, but can it be unplugged and discarded? I don't have the layout sorted for the wiring yet and I'm a bit boggled!

can you relay to us the numbers on the relay, as well as wire colors


IIRC at least one of those is a light/indicator/gauge relay

i had one of those go bad
another is a flip up control relay for your light motors possibly

i dont have a manual here right now to confirm though

I've scoured my manual and I'm still lost - probably being stupid and blind.

The relays themselves have no markings on them, but one of the rubber mounting sheaths has some legible markings:
51580
40840
12V 20A
OMRON
3110D6

The wire colours from the harness to the pair of relays are:
Black
Black/dark red stripe
Black/dark green stripe
Blue/yellow stripe
Blue
Blue/black stripe

From relays to the plug labelled oil cooler:
Green with red bands
Black/red stripe

To the smaller relay:
Red/black bands
2 x Blue/red bands
Blue/red bands and black stripe

I'm am concluding that this must be the control harness for the A/C cooling fan and other gubbins... I think...

did they look like this?

Do you sleep?

No, I had a pair like that on the other side - only kept the one for the horn. They are a similar size, but mounted in tight, black rubber condoms.

[freshlikesushi]

ahh ok. cant help you then good sir

I sleep, but im in saudi arabia, so a diff time schedule

[Toed64]

Thank you for trying - I'm very grateful. Time for more multi-metering.

We have Saudi-like weather today...3rd consecutive day of sunshine with no rain! ...and I'm building a car with no roof, doors, windscreen...

just looking in my manuel shows two relays on ofside wing for air con also talks about a single wire going to compressor i would think that would be quite a heavyduty wire .i would disconect connector and make sure everything still works. PETE.

Thanks Pete - you have a better manual than me! I had another look at my other Eunos today. It has only one relay in about the right place, that's why I had not thought it was the same part of the loom... but the wires are the right colours! Result - more snipping - after checking of course.
