props on the wiring... I definately would of had my All-trac up in flames if I tried anything like that... what's w/ the temps that you speak of (starting temps)... do they have to be a certain temperature to start the car? I'm lost... (as always)

Everything is workin great, i grounded my IC waterpump so its on all the time. I have had absolutely no problems, it runs a lot smoother under partial throttle now, probly since i was runnin the 185 isc.

My A/C doesnt work, but the light for it does come on. I think ill just have to put a manual switch to turn the pump on.

I've seen a lot of people stating temps like that so I thought I would ask.

well if you rewire to a 185 ecu and get it to work then you can always use PnP systems like the aem!

Hmmm can't see why your AC wouldn't work? Sure there isn't a way to make it work through the ECU?

i have three 165 ecu's ,also one complete 165 harness and one cut near the ecu plug area(jdm swap)- my current harness is a completely custom 165 harness(by custom i mean it was built from scratch by a rally team with two quick disconnects for easier engine swaps between stages). as much as i would like to go stand alone- its probably less expensive to do a 185 ecu as there is more aftermarket support with electronics for the 185ecu. whats the chances of getting the same setup???

for what it's worth, OBDI hondas use the exact same plug as the toyotas. a lot of the civic/common ecu's are hard to find, but there are some bastard child boxes that no one wants that should be pretty cheap.

the plugs are made by AMP/tyco too, so if you're doing a large volume of them you may be able to get your hands on them from the manufacturer.

female receptacle is amp/tyco part # 174518-7

the male plugs are part #'s 174514-6 (16 pin), 174515-6 (22 pin), and 174516-6 (26 pin), with contacts being part #'s 173631 (large) and 173716 (small). you'll need 16 of the larger and 48 of the smaller ones.

i can do even better than that :D

www.onlinecomponents.com stocks all these parts.

the female plug costs ~$6

the male plugs cost ~$1 each and the pins are about 4-5 cents each and they have no minimum order.
