The ECU relay is malfunctioning on my JDM EJ20TT and I need to replace it.
Problem: have no idea were to get JDM parts like this(I live in Belgium)

Does anyone know if other EJ20 engines use the same relay as this one? Can you guys check your's please?

the folllowing is written on the relay:
RELAY 2M
25229AA001
MR5A414A1K 12V
60611V JIDECO

If I can replace this part my engine should work again finally

Sorry I can't help you on getting a replacement, but if you get stuck and have the wiring diagrams you could replace it with two conventional everyday relays with a little bit of rewiring.

Don't have the wiring diagram either, I only have the ECU pinout

I had the same problem and Brad gave me this advice too. Find the wiring diagram. I know it's a pain in the neck, but these relays are hard to get over here too, even second hand. I was lucky and found one second hand for $10. Subaru charge like $110 for ONE of them.

You might be able to work it out using the old coil... break her open and have a look. Two wires will be going to the coil, these will have to go to the coil of the new relays (terminals 85 & 86). I'm guessing the other 4 wires are two sets of Normally open contacts (you can confirm by having a look at the contacts, if there is a gap when the relay is unpowered then its normally open). Normally open contacts on an everyday automotive relay is terminals 30 and 87. Alternatively if you can get hold of a double pole (DPxx) relay, that could do the job with just the one relay.
If you break open the case, you might even be able to clean the contacts up a bit and get it back up and running.

got lucky and found one on a eurospec legacy that works.

were I'm at so far: the ECU doesn't give the negative signal to the brown relay in order to activate it but if I put a negative on it myself,the ecu does power the spark plugs and I can get it running (badly) if I connect the fuel pump relay directly to the battery instead of the ECU powered fuel pump relay....?

probably, but remember the ECU switches the EFI pump on and off. still I guess that's what the pressure valve is for. also, you may get a fault code. the fuel pump relay is green, I'd check the liberty for that too if you can still get to it.

update: the fuel pump relay works so that's not the problem.
Discovered that the timing belt jumped 1 tooth, will put a new one on this weekend.

Could the timing belt be the cause of the ecu not powering the brown relay and fuel pump relay?

no I think the issue is you inter lock from the ecu not seeing the shifter feed paulse .in sort look at the diagram you will see the wire I am talking about

could be seagull but before I fried the loom, it was hooked up exactly the same as it is now and it worked.

I'm waiting on a diagram for my 3 plug ECU and I'll check it out, that shifter feed pulse might have cotten interrupted somehow.
