Picked up #239 on Monday and it was flawless! So now I want to make a minor change and add a better rearview mirror. Ordered a GENTEX mirror with auto dimming, compass and homelink. The removal of the old mirror was easy. The new mirror is a bit wider but i have no problem with it. Ran the wires and tucked them away. Now I need to tap into the wiring harness. So here is where I stop. I need some help to find the ignition wire and a wire that has constant battery feed. Since I don't have a shop manual and I don't want to just start tapping wires can anyone help me in this area???
Please help. If I can get it to work, I'll post it the results and the model # mirror.
I think I just may have found a solution without tearing the car apart. I found a mini jack that plugs into your fuse box that will allow you to run accessories without cutting or "tapping" into wires. As soon as I get them, I'll post my findings and let everyone know.
Finally got it to work. I did not see any pigtail for the mirror upgrade. Did pull down the overhead console light unit. All the wires were located right where I thought they'd be.
Here's where I had trouble. Since there are no instructions to install the mirror (eletrical connections) for the FIAT 500, it was a process of trial/error and a couple of blown fuses. (so buy any extra box of 5amp mini fuses) The mirror came with a wiring harness, connectors, etc.. that contained all the connections and the three wires. All clearly marked. Great product.
I used the center wire from the overhead console for constant contact. Tapped in using a tap that anyone can get from a parts store.
Here's where it got a bit perplexing...
I had to run two of the the wires from the wiring harness to the fusebox for the ground and for the ignition/switched power.
Ground wire was easy, just connect it to the bolt that you see when you remove the fusebox cover. (10mm)
I then used a MINI ADD-A-CIRCUIT, connected it to the switched power wire. (I had to cut the end off of add-a-circuit and then use one of the male connectors that came with the mirror). Easy enough to do.
The add-a-circuit will allow you to to use two mini fuses (5 amp). I plugged the add-a-circuit into FUSE # 13. Check your reference guide page 59 and you'll see it is for the ignition and climate control.
And it worked for me! Mirror dims, compass works, and the Homelink opens/closes the garage.
Now, someone may figure it out on how to use the connection from the overhead console, but I had a heck of a time. So I did it my way.
I don't want anything to hand from my visor. I want a clean look.
BTW..the standard 500 mirror is 9" The replacement mirror is 11" I have no problem with the xtra vision.
