Kade swap question

[poundit]

Ok so my single cam took a shit on me and I got a s13 dual cam for free all I need is ps, wiring, ecu, etc. so I'm wandering is if I need to get a s13 dohc harness and ecu or would it matter if I mix matched. Sorry ahead of time if this is a common question and thanks in advanxe

you need dohc wiring harness and ecu. Never did it, but I am pretty sure.

So as long as its a dohc ecu and harness I'm good? S13 or s14 doesn't matter?
