i've been on here numerious of times trying to figure out the converson harness for my
99 civic. but after ordering the wrong one (one that people told me would work) im back again.

SO here is what i got and need to know.

99 civic- obd2b
with 98 LS motor B18b1 obd1 out of a 98 Integra RS

Civic was AT, but converted to MT. Im guessing they used the civic and LS harness pieced it together to make the car run because i have 3/4 connectors going into the ECU. last i heard AT have 4 connectors.

so if that is all right anyone know of a place i can get a AT-MT converson harness?

 

anyone?

 

bumpoo??
no one on here knows where i can get a AT- MT conversion harness?

 

better off just getting a new either obd2b harness either ex or si would be best so u dont have to wire vtec.... si would be a better harness for the bigger dizzy plug

 

then ud need a obd2b-obd1 ecu jumper since ur not gonna have a crank sensor and MAYBE a Dizzy conversion harness, depending which way/harness you go.

 

The AT has 4-plugs and the MT has 3-plugs. Either one will work on a MT car, the 4th plug on the AT is for the auto tranny. You will just have extra plugs on the harness. And the harness has to be from a 99-00 civic

well i have the p75 ecu from the teg in the car and its plugged in, but their is a prob. the wire for the Speed Sensor is on the 4th plug which is disconnected in which i don't have a speedo, thats the main reason i need a conversion harness.
