Default Power antenna wire question.

My new H/U does not have a power antenna wire so what do I hook the wire that raised the antenna when the stereo is turned on to?

Nevermind. Looks like I just need to use a remote ignition source.

If it is an aftermarket HU it should have a blue wire. That blue wire is the "remote turn on" for power antennas and amplifiers.

Why a relay? I found a switched source going to the TCS switch and spliced into that. I figure it's not using that much power. Do I really need to use relays. Here are my 2 remote hookups.

Deck remote to 2 Diamond amps (D5600.2 and D51200.1)
TCS 12v switched to Power antenna (convertable switch I made) then to the antenna motor. If I need to use relays, which ones should I get. Never have messed with relays much.

Thanks.

Lots of reasons, one is isolation from the circuit that your tapping into and your amps. Another is amperage draw. With a relay it will only pull enough amps to kick over the relay which is a very small amount. You can also get amplifier pop on/off with some sources. Basically its insurance.

Let me ask you this. Your antenna wire, does it lose power when your listening to a cd

Its pretty eays to hook one up....

Heres what the bottom of the relay looks like



Heres the diagram


86 = switched on wire (such as ignition wire)
85 = ground
30 = to your amps
87 = 12v (from your battery)


Youll need one 12v relay you can pick up at radio shack (usually 30amps) and some spades

Cool. I might look into getting a couple relays. My antenna is always down unless I hit the "top" switch. I made a custom switch using a verts tcs plate with holes for tcs and top.

Antenna would stay up even when playing a cd. No antenna wire from the HU.

There is a write up somewhere. I have all my wires taped up but I believe it's the pink wire.

Here:

Here is the writeup for the power antenna switch. It's not that hard. If you already have tcs you need to buy the convertable plate and top switch.

What's the 87a pinout for?

Also, I'm only using the remote from the H/U for 2 amps in which neither pulls many amps on the remote in. Would a relay still be needed.

The other ignition sources I spliced I only did for switched power.

I'm using the TCS switched power for the antenna switch which is totally independent from the H/U. I'll probably use a relay here since I'm guessing the antenna motor pulls quite a bit of amps.

The only other place I spliced into is for the PAC steering wheel controls which seems to pull almost no amps at all. Doubt I need a relay here. Correct?

87a goes to nothing in your setup.

87a would be used for when the circuit is closed in a different application.

In your case 87 would go to the cd player
