Hi All -

I want to add a radio source (actually a Bluetooth receiver) to my dash of my 1970 FJ40. Can someone give me a specific way to wire from the fuse block (I.e. for power to the BlueTooth unit).

I have read other general posts where people say it is “easy” and to run a relay straight off my battery powered off/up by my fuse block, but I am looking for specifics (what relay unit, wire size, what terminal on the fuse block).

Wiring is definitely not one of my strengths and I don’t want to screw it up.

Thanks for any help!
 
I would just run a wire from the battery with a fuse to your unit. If you forget to turn it off, it will kill your battery, so some sort of indicator LED bulb to remind you its on could be useful. My 72 has no accessory position on the iggy switch
 
Not sure the power draw of the unit your buying but adding a relay that has a 12 volt DC coil that powered when the key is on then have a direct fused circuit from the battery is the way I would go. Then the unit can only work with the key so it doesn't drain you battery if left on. Plus the radio isn't using wiring from 1970 for power.
 
Listening to the radio while moving in my rig is more or less waste of time - the HAM might work. CD's don't bother it fides to rough, tape or digital might be ok. Usually radio/music is for when I'm stopped so I don't want the ignition on. Now my smarter than me phone has taken a lot of jobs in a small tracking device.

Interesting I have a some double DIN head units with a six CD changers that were used in Toyotas around the turn of the century that do amazingly well on rough roads. I also have a number of single DIN units with either a cassette of single CD player. Those allow for a add on CD changer. The double DIN would need to go in an over head tray. Remote CD changer can be mounted anywhere. They can also be mounted with cushioning to help with skipping. Because they are head units it's possible to upgrade amplifiers. Along with upgraded speakers and more of them can over come the noise in a 40. The six CD head units also work with the remote CD changers making a total of twelve CDs loaded at once. I have quite a few cassettes dating back to the 1970s. But that nothing to compared to the CD collection. Have a ton of LPs and 45s. Downloaded music I have zero. It's an age thing.

This is my garage audio which mostly dates back to the 70s and 80s.

If you just want blue tooth, there are several small amplifiers on the market that are blue tooth capable and you won't have to hack up the dash. I use one like this and just stream from my phone. You can hide this in or under the center console or seat.

I used the wiring for the interior light (missing) and put the blue tooth amp in the glove box. Factory switch to turn on/off. Have to remember to turn it off. Works pretty well, better than the boom box on the front seat I had for years.

Is that a set of Nova-8's?
 
I had a set of NOVAs in college, 6's I think. I got them for free (what I could afford back then) and had a Marantz receiver that I fixed. Mainly listened to OTA FM radio and secondhand LPs on a cheap TT.

Nice collection of vintage speakers.

Sorry for the hijack

Though I normally tell eveyone to go straight to the battery through a fuse, your 1970 has a spare fuse in the fuse panel you can use for the radio/bluetooth or whatever. Third fuse from the top of the fuse panel is the spare fuse. This fuse has power when the key is on or in the ACC position.

How to wire
Run two 16ga wires from where you plan to mount your "radio". One White/Black for GROUND and one Blue/Red for power. Connect the Blue/Red to the spare fuse output. Install a 5/16" ring terminal on the White/Black wire and mount that under the top mounting bolt for the fuse panel for your ground. On the other end splice those two wires to your "radio" power and ground.

Great information. Thank you so much for answering this!
