Help Identify These Plugs For Obd0-Obd1 Swap, Stock 91 Si Harness. What color wires go to which Obd1 sensor?

 

pic 1 = 3 sets of wires, Where do they go? IACV? Fan Switch?
pic 2 = I was able to figure out yellow/red is oil temp sensor, plugged right in to d16z6
pic 3 = Is this the right connection for tps, using the obd0 connection?
pic 4 = This one is tricky, but can i use the purge solenoid on the z6 IM instead of firewall? Do i just modify the obd0 plug on the firewall to fit the obd1 on the IM? Run 1 vac to IM and the other to the cannister?
pic 5 = Is this the correct connection for IAT (wire colors)?

 

Ok i just also found out that these 2 wires that had 2 banana plugs on them are for the fan switch, can someone confirm this, as i would like to splice, solder the correct obd1 plug to the thermostat housing. these wires went on a 2 prong sensor on back of the d16a6 block. is this correct?

 

black/yellow and blue/yellow= IACV Correct? need verification

 

ok so i seem to be answering my own question's here...lol might be helpful to other's perhaps.

So using my 91 Si Engine harness which is obd0, heres what i have so far:

Blue/yellow & Black/Yellow = IACV
Yellow/Green & Black = Fan switch Change to obd1 plug (goes to thermostat housing)
Yellow/red = oil temp sensor (back of block)
red/white & green/white = IAT
yellow, green/white & red/blue = tps
Map sensor is on firewall just extend 3 wires to reach TB, witch now has Map sensor on it.

Now the only one i have a problem trying to figure out is pictured below, Purge solenoid valve.
The d16a6 had one on the firewall, do i extend these wires to reach the PSV on the d16z6 IM?

If so no problem very easy, so now my question is where does this set of wires go? originally they went to i guess, the egr valve? Do i need the egr valve for obd1? can i eliminate these 2 wires?

 

black with yellow stripe and solid blue went to the Fast Idle Control Valve (pictured) on the back of the D16A6 intake manifold - you can eliminate them - only D16A6 had the FICV

 

tps wiring should NOT need to be modified since the car is already mpfi. the tps wire swap is ONLY for dpfi to mpfi conversion

 

cool so it's not the egr, it's the FICV. so eliminate these 2 wires since we are using IACV? Is their anything else i missed to turn my 91 si obd0 engine harness into obd1? Besides jumper harness...!

 

I was thinking i had to depin and swap a couple of wires, thank you. So only for dpfi to mpfi would someone need to do so.....good stuff.

 

Sorry last question, do i extend the plug on the firewall for the purge solenoid to reach the one on back of the d16z6 Intake Manifold?

 

Morning bump for an unanswered question, anyone?

 

yes

 

Thank you.
