How do you install electrical wire connectors?

If you're talking about an outlet - or a similar concept fixture - the best tool I've found is a flat head jeweler/precision screw driver.

The wire is being held in by this:

You can see you'll need to push that "tab" away from the wire, from the back of the outlet you should see a small rectangle hole next to each circular hole that the wires are in:

MAKE SURE POWER/BREAKER IS OFF YOU WILL BE TOUCHING A "LIVE" WIRE Insert a small jeweler screwdriver in the rectangular hole/slot, use the box as your pivot point and the screwdriver as your level (bring back end of screwdriver towards wire to force "tab" away) and gently pull the wire out.

* If the outlet is old/weak or the wire wasn't inserted in deep you can sometimes get away with just twisting the wire back and forth while pulling.

DIY: Installing a 4-way waterproof wire connector

Though I was unconvinced, out of sheer frustration, I agreed for the wiring to be cut. That the issue was not resolved and the ECU was eventually replaced to rectify the problem is a matter for a separate discussion. The cut wires were wound back together and insulated and I was unhappy with this setup, though the CC worked fine. I wanted to tidy it up.

Decided to install 4 way waterproof connectors. Ordered from


The installation is straight forward.

Step 1 - Cut all wires to equal length and remove about 5 mm of insulation
Step 2 - Slide the small yellow seal onto the wires and crimp male pins to one set and the female pins to the other. The inner flaps on the pin crimp the wires, while the outer flap crimps the yellow sleeve to the wire.

After these steps, you will be left with this -



Now slide the pins into the respective connectors. Make sure you follow the right sequence in both plugs. If you manage to get it wrong, taking the pin out can prove to be harder than one would imagine. Straighten the wires and apply insulation tape a few inches apart to keep the wires together.


Now slide a piece of corrugated plastic tube (with a slit cut through its length) over the wires to protect them from the harsh engine bay environment


Now connect the plugs together, tie up the piping to the firewall and you are done

When my ECU failed a few months back and the car had to be towed to KHT, the initial diagnosis was that the fuse box under the steering had failed. When I explained patiently that this component was just a stack of metal sheets, cut to form circuits with zero electronics and zero moving parts, the next culprit was the cruise control wiring I had done.Though I was unconvinced, out of sheer frustration, I agreed for the wiring to be cut.
