ok...im having a problem! i have a 99 honda accord ex sedan with the f23...and i swapping in the f20b with ecu...obd2... where im stuck is the dizzy wiring. my factory harness has 4 wires to the dizzy and the f20b has 8..i been looking around on how to wire this up...n from what im hearing is that i need to wire the crankshaft sensor plug from my wire harness to the f20b dizzy..?? is this true? n is there anything else i have to wire up? thanks

 

Well, on your 99 F23 the CKP and TDC sensors are down at the crank. That doesn't mean you use those sensors, because the F20b ECU will be looking for the collection of sensors in that distributor. You need to run the wires to the distributor.

 

ok...well i guess i gotta figure out which color goes to what since the all dont match up...does neone out there know?

 

Its crude but look at this.



I had to go through the same thing, as I used to have an F20b.

 

thats not what my f20b dizzy plug looks like.....that looks like the jdm 97-01 h22 dizzy plug!!! mine is def different.....

 

just wondering if you figured this out

 

Yes I did....I had to get some Honda guys from the city to come figure it out for me....it took them 5 mins....lol over a month a research n I couldn't get a straight answer....lol r u in need of help?

 

Nope I just ran the wires from the crank over to distributor lol.

So you car is running though? if so what ECU you running?

 

I'm running the f20b ecu....my car is a automatic....but the standard fuel pump in the accord won't run the motor right...so I had to buy 255 fuel pump...once I put that in....it's a beast! It revs all the way to 8k...if I push it hard I can shift at 8 k thru all the gears....i also have jdm f23 tranny in there...cuz the f20b auto tranny they sent me was bad ....so I have to get it fixed still

 

What do you mean the fuel pump won't run right?

Gotcha Yea I have a 2000 Accord Ex Manual though and I put in an H23a Vtec. I have the PCB ECU but wouldn't run my coolant through( fan never came on). but I drove it two days ran good just turn a/c on.
