how do i hook up my hondata s300 and b18 wiring harness in my 88 crx? right now the ecu isn't getting power? appretiate any help

 

you have to solder the s300 into the ecu.

 

its already been soldered in. the ecu worked in my 97 hatch. i just dont know what to wire? i have the main wire coming out of the wiring harness connected to the fuse box under the hood. is there more wires to be connected?

 

is you car obd1?

 

i dont thnk so....its a 1988. the ecu was hooked up in a 97 civic.

 

dont u have to use a obd1 ecu with hondata also?

 

You must convert to OBD1. Just changing the ECU will NOT work.

Get a OBD0-OBD1 jumper and change distributor and you'll be good.

 

wait...sowill myecu and wire harness i have in the car now work with this jumper? how come the distributor will not work?

 

ok you need a obd1 ecu with s300 soldered in. Then you need a obd0-obd1 jumper harness. obd1 Dizzy Also a 4 wire 02 sensor
