I am hooking up my aftermarket air fuel gauge and i am wondering which wire on the ecu do i hook it up to it is a 93 del sol with a p28 ecu 5 speed

 

any help would be nice like pin out ,color of wire.

 

all i need to know is which wire on the ecu i hook my gauge wire to there are to o2 wires on the pin out which one do i hook it to

 

o2 signal... i think it's the white wire on the o2 sensor..don't quote me on this though... could be the green one... you can easily test it with a multimeter... the heater power wire has constant voltage while the signal changes based on A/F ratio..should be easy to figure it out..

search for the ECU diagrams that are floating all over the place here.. you should be able to figure it out

 

Based on this:

O2 signal is the white wire, green is signal ground and the 2 black wires are heater power and ground

you want the o2 signal (white) wire..

good luck!

 

yeah but which one on the ecu plug is the right wire i use? thats what i am wondering about thanks for the info anyways

 

well you can run it straight from the o2 through the firewall to your gauge...

or if you want a cleaner install, search here for ecu diagrams to find the correct ecu pin

 

yeah thats what i am wanting is to the ecu but there are 2 diffrent wires on the ecu thats my problem

 

D14 is your o2 signal

only one problem thats a p30 i have a p28 ecu
