i currently have a d15b7 and i was hoping to swap in a b16/b18 soon (once block arrives) what special wiring do i have to complete beforehand to get everythign to work? all is obd1 and my car is 93. so would the ecu plug right in? and what will i have to run form the engine itself? are there more sensors? or will the wiring off the d15 plug right in and just run the wires for vtec selenoid....

any advice and or input would greatly be appreciated

 

The easiest thing to do is get an obd1 b series vtec harness, then youll only need to run the vtec wires and possibly a knock sensor wire from the strut to teh computer. You could just stretch your current harness and add wires all the way but its not the best thing and youll need to get some plugs. Any other obd1 computer will plug right in, a chipped p28 would be your best bet.
