i will be putting a b16 into my 90 civic SI, can someone uickly lay out a rough guide to wiring? like do i have to rewire every wire int he bay to the plugs on the b16? or are the plugs the same? how many wires do ia hev to add and do i have to move any wires ont he ECU plug to make room for them?
any responses would be greatly appreciated, as im going to be doing this swap very soon

 

you only have to add 4 wires, if you have an si. If you dont want to tackle it yourself then check out hasport.com they have wiring premade kits.
Run a wire from a8 to vtec sol. run a wire from c8 to secondary 02 sensor that you will or wont add( up to you)...wire tehm accordingly. run wire from b5 to vtec pressure sensor. and lastly run wire from b19 to the knock sensor. its really simple to do....good luck

 

d you have a pic of hte plug with the pins that do VTEC sol and such?

 

no i dont but should be easy enogh to find online...?
