I couldn't find quite what I was looking for in search so I'm making a new post. I'm converting my DX harness to MPFI for my B16 swap but I need to know what plugs I'm going to need. So far I've found the 4 injectors & injector resistor box plugs but all the plugs in red I don't know what they are or if I need them for this conversion. If someone could help that would be great.



If anyone needs specific pictures of plugs i can do that just let me know the number

 

bump - somebody's gotta have the answers

 

I assume that the picture is a Si donor harness and you're wondering what connectors you should splice into your DX harness.

1-3. Connect to the chassis wiring harness: don't need
4. TPS: don't need
5. Distributor: Definitely Need
7. Coil: don’t need
6/8. One is for the 02 sensor the other is for Coolant Temperature Sensor, might want to save the 02 connector to wire in the 2nd 02 used on 1st gen. B16As.
9. IAT sensor: (Intake air Temperature) Probably don't need
10.EACV: probably don't need
11. Alternator: probably don't need
12. Coolant temperature switch for the cooling fan- probably don’t need
13.?

Due to the picture quality, I'm not 100 percent sure.
Remember some connectors are the same on the DX and the B16A but their location on the engine changed.

it's just the 'other side' of the engine harness that connects to the body harness. It's either round or square depending on the year. the original 'dx' harness will take care of that.

but who cares. don't need it

i HOPE i'm not seeing red butt connectors in that pic. solder, heatshrink and high quality electrical tape are a must for a conversion unless you like to troubleshoot.

This is all awesome stuff! I'm not sure what 13 was. It has the yellow/black wire going from it to the Injector resistor plug as well as the solid color wires from the injector plugs and a blue/yellow wire.

sadly those are red butt connectors but once I'm doing the swap I'm going to do exactly as you said and leave the butt connectors out. I just happened to get the harness that way
