does any part of the engine harness have to be modified? right now whats not pluged in is the evap valve, iat sensor, and iacv. now i noticed all three of those have the exact same plug and there is only 2 of those plugs on the si harness. and there are a few more plugs on the harness that dont look like they will plug into anything on this motor. and last does the fast idle valve have a plug cause i cant feel one on it.

 

hey this doesnt really answer your qustion but why are you putting a D15B7 into your si?

 

IAT is a red/something and a green/something wire. (christmas colors)
EACV is blue and yellow/black

Tandem wires don't exist on your Si harness.

 

cause its allready in there and i need to get it running. i got the evap and iat figured out. what color wires go to the iacv? and there is no plug for the ect switch. and what does tandem mean?

 

ok these are the three plugs i have left. the big round one to the left has 2 wires black and yellow/green. the middle round plug has one wire and its yellow/red. the small plug to the right has 2 wires that are blue and black/yellow. only the iacv and ect switch dont have plugs.

 

im not sure about this but dont those plug into the back of the block? by the oil filter kinda?

 

i pretty sure theres no plugs down there. is the iacv plugs from a obd0 motor different from obd1?

 

the 2 slip on pins in one boot is your fan switch
Your D15b fan switch is a round 2 pin plug on your thermostat housing. Extend it to a 2-pin round. I'll ship you an adapter for $20.

the 1 slip on pin is your oil pressure sensor and should exist there.

 

so where does the small 2 wire connector farthest to the right go to?

The two pin connector to to right looks like a fast idle solenoid
which you can probably leave disconnected..
Other models had that on the firewall..

 

ok before i start cutting and sauldering does it matter if the wires are crossed? i have extra 2 pin round plugs but the wire colors will be different on them.

I just wired my MPFI swap and that two pin connector went to a pig tail off the IACV. I had to take it off my Si harness and put it on my DX harness.

 

ok that fast idle sylonoid isnt in that spot on the b7 manifold its under the throttle body and has no plug. what is in that spot is a evap valve and i dont know what plug goes to that and thats the only thing not hooked up right now.

so you saying that small plug goes to the iacv?

 

I'm sorry that plug goes to the IAT (intake air temp sensor) it is on the drivers side of the intake right above the alternator.

 

sorry I need some sleep on my 89 crx mpfi it goes to the EACV, that valve in your pic by the plugs. mine had a pig tail plug on it I had to take it off the SI harness.

 

no it doesnt go there either that plug wont plug into any thing on this motor. im pretty sure 88dxcrx has it right so im gonna leave it un plugged. now the only thing i gotta do is saulder a plug for the fan switch but i need to know if it matters if the wires get crossed or not. any one know?

d15b7 with the a6 cam is actually faster than the a6 in the si...
