eh, i'm swapping in a '94 D15B7 into '91 Civ CX for school. i searched but can't find out what i should do about wiring... will i have to buy an ECU adaptor for the cables in the firewall? how will i modify the B7 harness for different plugs, or should i use the '91 harness and wire in the injectors? the old ECU is a PM5 that will only run a DPFI system. any knowledge would be awsome. this isn't a performace swap (that'll be later) so i think thats why theres no info on it. thanks

 

bump, anything?

 

Use your stock harness..Convert it to mpfi and obd1..Then use your stock cable tranny or find an si one or whatever..Or you can stay pre-obd buy using a si or hf dizzy on the d15b7 and use a mpfi pre-obd ecu..Either way you will have to convert to mpfi..

dont use the d15b7 harness ..Thats the hard way..Keep your harness and make it work ..If you can make your own harness you can check out rywire and they can prolly make you a harness for direct plug and play..
