Dpfi To Mpfi To Obd1, lost now Options

[phatboycrxhf]

so all was good untill i messed up ,pretty sure anyways haha ive been lookin around online ,but i found so many write ups,which are pretty much the same for slight diffrences ,but anyways

here is some pics

what is this plug ? ive been told the coolent temp sensor

but isnt this one the coolent temp sensor ? which has a ground on it as well that bolts near the thermostat housing


allso what is this plug ? intake air temp ?


when i did the dizzy plugs from dpfi to obd1 ,all seemed good untill i noticed the wires didnt match to the write up ,well they did ,but for some reason i had the blue wires which goto c1 and c2 not blue white and blue yellow ,but wewre blue white and solid blue .which is fine if the timing is retarded i'll just switch them,but for some reason i have this white wire and this yellow wire ,so i just put them together and hopeing for the best.


so i did everything ,like add the injector wiring and get rid of the resistor box and wired obd1 injector plugs so i know thats good ,its just these last few plugs that are getting me


pretty mucht he harness looks like this right now

so damn close just a few loose ends to figure out anyone able to help me out ? i'd really appreciate it

there is no reason for this to be as hard as its been. like this is getting silly to be honest

Without wiring colors i cant tell you for sure on the first pic, i cant think of a opaque green 2 wire round connector thats not one of the injectors on the DPFI harness.

The 2nd picture the 2 bullet connectors in the rubber housing is the fan temp switch. Turns on and off the radiator fan.

The 3rd picture the clear/tan translucent 2 pin connector with those colors should be the coolant temp sensor in the head for the ECU.

first ones colors are blue/yellow black/yellow ,the second one should be go to now then .thats good

do you know which plug is with green/white red/yellow colors ? pretty sure i sent that one as the coolent temp instead of the green white red yellow. is that the intake temp sensor? is that what its actually called ? IAT i know i dont have anything going to that guy so one of these plugs must be for it haha

thanks alot so far man

Blue/Yellow & Black/Yellow is IACV, idle control valve.

Yea the IAT and IACV and ECT all have the same plug setup so you can interchange them, If you do mix them up it can fry the ECU.

Youll just have to get out the book for whatever engine harness your modifying, if its a 88-91 DX/STD Civic/CRX and see what wiring colors they used for IAT and ECT.
