Newbe here. I picked up a power antenna from a Galant at the pick n pull yard and want to install it in my 1986 4Runner. The harness has 5 wires. A black with 1 silver dot and a black, red, blue, and white all with 2 silver dots. I haven't bought a deck yet but when I do, how do I go about wiring this up?

I can't be bothered to pull my Galant apart BUT 2 thoughts, Google Mits Galant wiring for the answer, it IS there and that's a flat top, you might need a top conversion for your vehicle.

I found the diagram.

Question: Does the antenna require a positive or negative trigger?

Positive, all car radios give a pos output for antenna and amp.

careful Howie...old Mazdas (from the 80s) had negative triggers for the power antenna.

Really? I remember some Toyotas used twin triggers at the head unit.
But then I haven't done any auto aerials for what 3 years or cut any holes for 6? Built in, sharks fin, on the roof, never get to them any more. I fondly (don't) remember carefully measuring off the hole position (early80s to mid 90s) on W124 Mercedes then using cone cuts to oval it out.

I spent much of the late 90s rebuilding the damned things, using bosch timer relays etc. I even found it was cheaper to buy the masts from a Vauxhall dealer (Euro GM) than Hirschmann! I also had an account with Nippon Antenna Co. who were supplying Rolls Royce, ended up selling on to my local dealership because they were paying Rolls Royce inflated amounts for them. One of their units was a ringer for the 6000 series with rubber tops but better! Bit of muck on the telescopic parts and say goodbye Hirschmann.

Here's a plan for bringing power to the antenna.

And I found this fuse block that will fit between the battery and the fender.

What? SINGLE fuse from battery, ground, ignition trigger or antenna trigger from radio, most antennas have built in relays, have you tested it yet? This is going to cost you more especially the labour than just going out and BUYING an aftermarket antenna.

I'm trying to follow the galant factory diagram. The relays are so I don't overload the existing circuts. Yes, i could have bought an aftermarket power antenna for $35. I thought picking up an OEM one at the local junk yard would be a higher quality unit, with no shipping posted_image
