im pretty sure it hooks up to b13, 14, 15,and b16 there are 4 wires blue, white, red, and green on the crank tdc sensor...which ones go where? anyone? frustrated all to hell

got all the sensors hooked up except my crank sensor on the bottom of the motor...anyone have a clue which pins it goes to on a p13 ecu?

ahhh thanks much

yea i have that printed out already...if someone could just explain which pins are which cuz on the ecu there are 2 rows of pins

the sensor on the bottom is crank fluctuation sensor... the sensor on the throttle body is map sensor and i know where the solenoid is... really....the only confusion that i still have is the ecu pinout

Ran into some wiring confusion. 3 things: 4 wires coming out of the bottom rear driver side of the motor...dont know what it is but it wasnt on my h23 vtec pressure switch is on the top of the throttle body...right? it has one wire and i have a general idea of where it plugs in on my ecu but...

I just talked to another dealer and they are saying that if i use the p13 ecu i wont need an adapter harness and that they actually dont make an ob1 to obd2 harness.

98 its an h22a4

Not sure if i was misinformed or not but i was talking to a hondata distributor and he told me that i wasnt going to need an adapter harness and that i needed an obd1 ecu. Im really confused right now :blink:

the motor is in and tomorrow i have to go get a distributor and my ecu. The motor came out of a 98 prelude and my prelude is a 92. Will the p13 ecu from the 4th generation vtec prelude work for me? and ill need an obd1 distributor also...right? If anyone has done this swap any wise words...

So i want to get an obd1 ecu and an obd1 to obd2 conversion harness? Im still unsure about which ecu i am going to need to get. will a p28 ecu work?

I have a 92 si prelude with a blown h23a in it...i am going today to pick up my h22a long block. What ecu do i need to buy and since my motor is obd2 am i going to run into some problems cuz of that? thanks

How do you wire a 92 si lude for vtec?
