WARNING:
1. If you want to sell the VAFC/SAFC later on you might want to reconsider doing this, since the buyer may or may not like the modification.

2. Be very careful when soldering because there is very limited amount of space to work with.


I've had my VAFC for awhile now, and the first thing i noticed when i got it was that the wire harness was really hard to detach and seemed really flimsy/delicate.

So what I decided to do was create my own harness.

Tools:
Soldering Iron & Solder
Shrink Tube
(1) 15 Pin Male Plug
(1) 15 Pin Female Plug
(2) 15 Pin Covers
and alot of patience


Here are the 15 Pin Plugs and Cover with some extra wire(more on that later)



First thing I did was cut the VAFC harness



This is how it looks with all the wires on the plug



Here is a picture of both ends soldered to their respective plugs



This is how it looks completed



The plugs fit together really snug and have not come undone by themselves. I am very confident that they will not come loose unless you physically pull them apart yourself.


And for the extra wire...I have always wanted to put my VAFC where I can see it on long drives, but since i did not feel like rerouting the cable from the harness. I decided that i would make another plug where i can mount my VAFC while still being able to keep the mounting point in the glove compartment.

So this is what I came up with...

I found a place in my car that would be most convenient for myself, so i chose to make a plug on the din pocket. This part is user preference.



this is how the wiring looks



Picture of it in the car



This is how it looks on. I still need to run to the store to pick up another APEXi mounting bracket.



Total cost of modification:



Personally i like the new mounting plugs, in my opinion they are much easier for me to remove my VAFC. Additionally i can either keep my VAFC in the glove compartment or keep it within view by my stereo without having to deal with rerouting the cords.

great job on your write-up, I could have used this like a year ago oh well

Great idea: Original, Clean, and Functional. We need more FAQ's like this LOL
Is that the same as a computer gameport plug?

Does it lose the settings if you keep unplugging it and stuff?

they are the same, the one i used is just a generic one. you can find them at any electronic store.

The only reason i didnt buy something smaller because the next one down was a 9-Pin and the VAFC has 11 wires.

I purchase all my stuff at a Orvac's Electronic in Fullerton on Raymond and Orangethorpe.

Nope...settings are retained until you reset them yourself

i got a wiring question. if i was to do this, all i hafta do is to make sure all the wires match eachother from both ends right?

AzntaggeR

damn that's clever. can't believe no one has thought of this yet. this how-to makes me wish i still had my vafc .

I did a similar thing with my Field AFC. I used Cat6 cable (6-pair) to go from the ECU to the cupholders... the wires in there are like 24-22awg. Anyway, the tach on the AFC fluctuates noticeably, like when driving at a constant speed, it would go up/down as much as 300rpm. The speedometer doesn't do it ever, seems 100% accurate (includes speedo in k/h). Do you think that the thin wire is the cause?

Nice idea! Will do this the next time I install a VAFC!

i don't know the cause for that, thats alot of fluctuation. Mine works just fine, works like the VAFC with the standard harness.
