there are many sorts of five pin relay for varying purposes.
TT |
Can someone point me towards the correct type then? I thought they all worked on the same basic principle.
|
What relay have you got?
|
My relay is one of these
http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=230493939634 I'm now also struggling with the flasher relay. It's not flashing, just giving constant 12v :( |
Is there a way to test the relays (especially the flasher), as i've been offered a replacement, if its faulty.
|
Have you got the lights attatched to the flasher?
The five pin looks like a normal changeover relay. TT |
I've not got all the lights attatched to a flasher, just the front ones. It's getting a 12v but not flashing???
Also, that's what i thought about the 5 pin, but that's causing problems too :( |
I seem to recall a problem on my sierra, try connecting another lamp. and see fi the relay begins to flash. In nor mal operation you have the load of 4 lamps (front,rear,side, tell tale)
What have you got connected to what on the 5pin. TT |
The 5 pin one is connected as per the v1.3 diagram in this thread.
I'll try connecting more lights this afternoon :) |

I've got my changeover relay wired up as per the diagram and seems to be working fine using the telltales (haven't fitted the full lights yet). I used the changeover relay (blue one) I found in the ford fusebox. Wiring should be to With regard to the indicators, I left everything wired up as it was on the sieera column. You need to earth the brown wire from the flasher relay. Then find the indicator wires on the column. Check the colours carefully against the diagrams as I have seen a diagram which you need to hold upside down. Not near the car now but I think grn/blk is the RHS indicator. Connect your lamp up to this wire, and then to your earth and the wire should flash, albeit at a fast rate. Did exactly this on the weekend and it is working fine. |
Got the flaher sorted. It was a faulty bulb in the light i was teting it with!
Still no joy with the change over relay yet. I'll have a go at that tomorow |
Cool, seems odd at first when it does not work.
Modern ones are often a timer relay but these old ones need a load to flip-flop. TT |
David, Any luck with the headlight circuit?
I would try pulling out connections 87 from the dip and main beam relays. When you change from sidelights to dip you should be able to hear (and feel if you put your finger on the relay) the relay clicking over, the same should happen when you go to main beam for that relay. If that's ok then I would check the changeover relay. If you can do a conductivity test, 30 should be connected to 87a when on no lights, sidelights, or dip (just to confirm that is based on continuity not voltage). When you turn the headlights on, the changeover relay should switch, and 30 should now be connected to 87. Make sure that 87 from the headlight relay (not 87A) and 86 are connected together. Cheers Dave |
Still no luck with it. Think i'll just try a new relay, that's all it can be as far as i can see.

Great thread and very useful. I'm in the process of pulling my loom from the doner (2.0i DOHC) and after reading this and a few comments on other threads from TT, I'm really reconsidering using the original loom due to the amount of junk in it that I'll spend days identifying and cutting out. Can anyone tell me how much the wiring diagram in this thread would change for the 2.0i dohc? I know that the ECU will need to get wired in but can you think of anything else that is not covered in David's wiring diagram? Cheers Matt |
Without knowing the wiring of the DOHC generally the loom will stay the same apart form the last two (ignition and fuel circuits) relay circuits on the last page. TwinTurbo is the man who can probably help you on the specifics of the DOHC ECU
|
All sierra's have a stand alone engine loom, they are connected to the body loom via 3 connectors. the DOHC usualy conforms to the post 90 wiring. the best bet it so remove the engine loom and salvage the plugs that it plugs into.
More details of the plugs ( not totaly complete ) can be found on my website, although it's aimed at people converting to the 24V v6. TT |
What size wire did you use from the mega fuse to Relays/fuses Ect..?
