racerrick · #1 (**permalink**) 10-24-2010, 02:11 PM

ok here we go 92 prelude with a jdm motor and a us harness. ended up with 2 extra wire connectors.1 is green 2 wire in the dist harness.the 2nd is on the pass strut tower and is gray 2 wire.(see pics) the fans do not come on and the check engine light is on.is there a way to pull codes with out a scan tool?
does any one have a vacuum hose routing chart? thanks for any help you can give us

it is a f22b took the h23 out

you should specify what engine u have. i have those same wires and my car runs fine i have the jdm f22b, the check engine is prolly because the f22b doesnt have a knock sensor. as for the fans idk.

where id the knock sensor located?

the knock sensor on the h23 is on the back side of the block under the intake mani. the f22b doesnt even have a hole for one they dont use it

the round plug lookslike the one that goes on the vtec pressure sensor ( the one that sticks out of the vtec solenoid ) this sensor is not on the obd1 jdm engines .. was your usdm engine an h22 ??? if so this sensor needs to be installed on the new motor ( if your running the usdm ecu ) ... as far as the grey 2 wire if its a big connector its for your fans .. trace the connectors back from the fan ... there is a connector ( 2 wire under the center console towards the front ) use a piece of wire to jump it out and the check engine light will flash you codes .. long blink is the first number fast blinks second number

green plug is for a coolant sensor, under the dizzy.

there is another green connector connected to the head. when you say temp sensor is that for the gauge or fan?

there are 2 green connectors for the coolant sensors, 1 is on the t-stat housing and the other is under the dizzy. i believe (could be wrong tho) they're both for the fans.
