What relays are shown in the pictures. I've looked in the manual and can only identify what I think are the pair of fan relays next to the rad in the top picture, but am only guessing. I've been chasing what I now believe is an ECM problem. I sent it off to SIA, they said it was non repairable and had a fractured board. I opened it up and really can't see an issue, but when I reinstalled it, the pair of fan relays and the one by the brake booster begin chattering!! Then they stopped and the fans went to high speed. Car starts but with the same codes. Module 1 gives a 41 and 54 and module 4 gives ERR and module 9 gives 72.
. Thanks
1st 2 are the cooling fan relays, next is Air Injection Reaction Pump and the last if it's the only one on that rear wheelhouse I'd think is the A/C Clutch. Are there more there or is it a stand alone?

Yep, it's all by itself.
So the top picture where I'm pointing is the relay for the Air Injection Reaction Pump? The 2 hanging on the rad housing are for the cooling fans? The one I'm pointing at in the last picture is the AC compressor relay?
Man when I 1st put that ECM in and just turned the key on, it sounded like a Irish Step dancing competition going on. Then it stopped and the fans went to high speed.
