 |
|
I have been using USB adapter plugs in cigarette lighters for years in my van and other cars, finally got tired of trying to find the plug and needed additional charge points in the Dash for additional electronics while road tripping. Still using the cigarette lighter socket for power
While looking for USB plug options I learned about inline DC 12v/12 volt stepdown converters. I already had an unused always on power connection in the dash, a branch of the radio/map light/cigarette lighter circuit. The circuit is mapped out in Bentley on page 97.199 - it is a 3 pin connector floating around behind or underneath the radio.
I crimped a couple of male spades onto the USB converter and plugged them into the T3 plug and wrapped the connector in electrical tape. The USB pigtail with its two female connectors rests inside the glove box ready for use anytime. The device is inexpensive (amazon) and the installation is non invasive if you have the unused connector available.
Here are a couple of images of the connector and the pigtail.....

That's weird — what the heck is that pigtail actually intended for? I've never seen that in our '91 van, and I've done some extensive digging back there.
What fuse is it running on?

The unused plug is for an optional amplified speaker that was installed in some carat models. This plug runs off of the radio/lighter/map light circuit. I am on my phone now, but the fuse is printed at the top of the wiring diagram.
