Unhappy Reconnect harness to ECU

Hi guys,

I'm at the tail end of my engine swap and I've gotten the harness back into the passenger footwell. Then I realised that I've FORGOTTEN to label the connectors, ARGH! Can anyone point me to links/pics with which harness connectors go into where, there are 2 pairs of yellow connectors that are kinda similar to one another that should go into the ECU. In fact, there are a few pairs of white and blue connectors that all look same . Anyone?

Thanks...

The harness to the left comes from the engine compartment and I assume plugs directly into the ECU. What's the white connector for?

And the stuff on the right was with the car.

The plugs can only go one way, just count the pins on the yellow plugs to the ECU. The white plugs are above the Ecu look there . Pull the seat out and lay on the floor so you can see and reach every thing .

Hi guys, you were right on the yellow connectors, they are all different. Now, here's the confloosing part, there are 4 blue connectors (1-4), does any one know if 1 plugs into 4, and 3 plugs into 2, or vice versa?

And the white connectors do they go together? although they seem to come from the same bundle from that black box above the ecu.

Thanks!

I have the FSM and wiring diagram, but being a stupid software guy, it made no sense to me...

FSM won't help too much on that.

That's the Fan recall messing with you.

If you remove the fan wiring then plug everything in it should only go one way. Once that is done "splice" in the connectors for the fan recall.

BTW that's not the only wiring they add............ god....... i fought with that forever as my fans woulds stay on incorrectly(-ok it was only 4-5hrs but felt forever). There is also a jumper added by the relays. I was look'n at the FSM scratching my head (and i love the wirng diagrams in the FSM)
