b16a wiring

what is the best method/tool for adding the vtec solenoid, vtec oil pressure, o2 sensore and knock sensor wires to the integ wiring harness. is there some kind of tool you use to push the wires down in there or do you have to solder them in? thanks for the help

I’m pretty sure there’s a tool to do that, I think honda may make one, and I think I recall someone mentioning that hasport or skunk2 or someplace like that makes one as well. Search around the internet and honda-tech.com and you may find the answer if someone else doesn’t post the details up here first.
