one thing im not sure about:

is it true that the ONLY thing i have to do for crank angle sensor wiring is at the ecu move pin c1 to b10 and c2 to b12. theres nothing i need to do out in the engine bay for this?

 

true that. thats it for the crank angle then just hook up c1 to the blue/grn and the c2 to the blue/yel for the cps on the dizzy.

 

then of coarse you need to run all vtec wires

 

also have to run a new wire for the second o2.

 

this is getting stupid...maybe im just stupid ok:

heres a pic of the b16a distributor connectors in my 88 si:


and heres the ones on the d15b2 in my 90 dx:


i havent read anything saying that the connectors are different....but obviously they are. can some clerify this.

 

The Dx distr connectors are different. You cant use the B16 distr with the dx distr plugs unless you have a matching set. Also, you only have 2 injectors on that dx harness. Start adding more wires.

 

In regards to the dizzy wiring, everything will match up the same if you convert the DX plug to the SI or B16. Run c1 and c2 from the ECU out to the dizzy plug. These will be the additional 2 wires that are "missing" from the DX dizzy plug. They are blue/green and blue/yellow.

Hope that helps.

ok so what about the injector resistor wiring: these are different too:

si w/b16
