I am doing the DPFI to MPFI OBD0 swap in my 90 DX and have the B7 intake/injectors , pm6 ecu, A6 distributor and injector clips. Where can i get the round distributor plug? Does anyone sell these new or do i have to find a used one? Thanks.

 

Junkyard or you can see if they got something that suits your needs for male and female connector set at say radio shack (or similar electronic store).

 

you dont need the round plug but it helps you can use the old square one and sodder on to the A6 dizzy then just get 2 single wire connectors for the cam sensor wires. you could even just sodder them together just need to cut wire if u need to remove dizzy. the junk yard is the best place to look. look for the A6 wire harness and just cut it. you can also steal it off other honda's just make sure it has the same wire count and its round honda plugs are more or less universal to the size across all models.

 

Thanks, i noticed that the TPS plug is the same and also the O2 sensor plug. The B7 intake didnt have the map on the throttle body so im wondering if the DX map sensor on the firewall will work for now?

 

Firewall map will work fine as long as you have vacuum hooked up to it.

 

What do i do w the EGR hose? Plug it off since i wont be using an EGR?

 

Yup. Just make sure nothing is left open (on the engine). You don't want a vac leak.

 

I noticed a hose running from the egr to map. Hope plugging this off doesnt cause a problem?

 

That's not really possible.
The EGR vacuum line goes back to a vacuum control valve, but it's not your MAP.

 

I thought that was the map on the passenger side firewall with the rectangular plastic cover that keeps falling off? 90 DX. There are a couple valves or dashpots under that i thought were part of the map. My bad. Any other crap that i can trash with the EGR valve?
