Default Need help on Dizzy wiring for B18B1 into the EF si???

This is what I figured.


si harness B18 dizzy
Blk/Yel -- Blk/Yel
Blu ------ Blu
white -------- Yel/Grn
Blu/Grn ----- white CYL
blu/yel ------- orange CYL
Orange ------- Blue/Yel Crank
white ------- blue/geen Crank
white/blu ----- white/blu TDC
org/blu -------- org/blu TDC

What do ya think? would it be correct?

(Just curious) What makes them not compatible? Second I wired my brothers P28(OBD-1) onto a OBD-2 dizzy, why wouldnt the same concept work?

obd-1 and 2 dizzy are the same kind, actually most are the same... even the plug, the plug was just made into one big plug not 2 like the obd-1. The pins are all the same. The obd-0 stuff is diffrent. Sorry it is a fact of life, even if it does start something will fry very soon.
If you wanna run obd-1 get an ecu, 4 wire o2 and conversion harness, if you wanna run obd-0 get an obd-0 ls dizzy...simple as that.

do not try to repin and obd 1 dizzy to run on an obd 0 ecu, you will do some serious damage

Serious damage to what? Dizzy or ECU
I already wired up the Dizzy to the wires stated up above but the car hasnt started or attemp to start only because the dizzy may have already been broken before the swap.

it will not fry, it will work but the timing would be wayyyyy off, it could work if you cut off all the tab and rwld them back on in diff spot, just easier to get a obd1 dizzy, stock crx will fit but you can only put 1 bolt on and it will not advance enough but will run
