FJO injector driver wiring
I have the unit that has 10 wires + 1 ground and 1 power. The wiring diagram says the white wire should go to all of the injectors. So how do I run one wire to four separate wires?
Another thing; can I utilize the dead end plug (the one with 8 yel/blk wires on the driver's side) to simplify any of the wiring?

You find the four ylw/blk wires that share a common 12VDC+ source from that distribution block and tie those four with the white/whatever wire on the output harness of the FJO driver.
The best placement for us in the Civic would have been on the frame rail or enclosed in a box behind the headlight, but the manufacturer specifications only allow for an ambient temperature maximum of 185 degrees Fahrenheit, and I was worried that vibration would hurt the unit eventually if I mounted it to the frame rail. So, it's currently sitting next to the ECU until I can work out a better solution.

Re: FJO injector driver wiring (IN VTEC)
i think its much cleaner to run a whole new injector harness. from your ecu the signal wires are going to go to the driver...and from the driver to the injectors.......so it just makes sense to run your power wire (split to 4) along with the signal wires. i ran a 6 pin DTM connector on my old set up right by the throttle body so i could pull the head/intake off with out having to unplug the injectors individually.

so 4 out of the 8 that are on that dead end plug are 12VDC? so i need to probe to find those, then i can hook the white to those?

Re: FJO injector driver wiring (IN VTEC)
i just checked continuity between the yel/blk of the dead end plug and each of the injector plugs and there was continuity between all of them. so each wire doesn't correspond with a certain injector, one wire powers all of them. does this make sense? how do i proceed to wire this sumbitch?

Re: FJO injector driver wiring (Mikey3000)
I don't think you check it right. when I put my oem injector driver, each of those yel/blk wires from the injectors have thier own yel/blk wires on the dead end plug. I am now going to install this fjo driver same as yours w/ 10 wires on one side and 8 wires on the other and I also need to know how to install this bad boy. Joe, can you please make a "how to install fjo injector driver" specially the one we have w/c are the 10 wires w/c are more difficult to do. thanks in advance. And maybe we can make that a "sticky" on here for people in the future.

mine has 11 wires total not 10 and 8. it has 6 wires on the ECU side and 5 on the injector side.

Re: FJO injector driver wiring (DaveF)
I have the older version fjo driver right before this one that dave posted. Dave, can you please help me figure out how to wire the older version? or anyone? I really appreciate the help. Click on the link and download the manual for the older version. There's so many wires to hook up, I"m confused.
