Fuel Wire Question

[Maddog2873]

I am hooking up my JB4 right now, and I am noticing the fuel wires have a millimeter of unshielded cable towards the end, right before a small section of shielded cable at the tip. Should I be removing that small amount of shielding before making the connection?

Yes, you take that entire "cap" off and put it into the positap to pseudo-crimp it.

A plug-and-play option like this is also amazing:

x2 Fits Stinger GT G70 G80 JB4 Lap3 Harness Fuel Wires Wire O2 Sensor Turbo AFR | eBay

These harnesses have the o2 sensor's AFR wire extended out so you can connect your JB4/LAP3 fuel wire easily without digging into the wires. The extended wire has an insulatedconnector installed and you will also receive the mating end with the harness so that you can crimp it on your JB4/LAP3's...

See the fuel wire install video for how the posi-taps work.

Yeah I took another look at the video and noticed no shielding on the end. Of course my sausage fingers managed to drop one of the posi-taps and it has been labeled a loss, lol. Nobody has anything around here similar so far. Might have to order a few spares.

@Terry@BMS Will JB4 do anything with only one of the fuel wires connected?

 

[Terry@BMS]

You'll wind up with uneven air/fuel ratios bank to bank and the JB4 may trigger it's fuel trim variance safety system.

Would that happen if I leave it on Map0?

 

[Terry@BMS]

If you only have 1 fuel wire connected just disable them by setting options bit0 on until both are connected. Map0 also disables them along with the rest of the tuning.

Thank you Terry! Ordered replacement posi taps, just have to be patient until they get here now, and hope I don't drop them anymore, lol.
