I have been looking at my fsm but the wiring seems to be different colors than it shows. I am trying to figure out which wire(s) on the ecu are for the maf and throttle position wires coming from the safcII. I have power to it and the tach wire hooked up but am having problems finding these wires. Any input would be great. And it is a SOHC 😃

Hello , what’s up
You have to use the N3-b diagram , count the pins and you will be fine .
I installed 5 afc’s so far and I never had a problem , You should be able to do it no problem .
The only dangerous part is to get the air flow right , The air flow signal needs to be cut so if you screw up , bye bye motor .
As far as the other signal wire , the worst case is that you will not get any reading . ( volt , trottle … ), you can even try and error if you want .
trust me it’s not hard , 10 min maxxxxxxxx
