360 ACC power for license plate camera install

Search function button doesnt seem work for me on Safari on IPad, so my apologies if this has been covered ad nauseam….. I went back through the past months threads and didnt see anything that answers my question.

I am installing a WIFI backup camera… I need ACC power line to tap for it…. Would prefer not to use the tail lights or license plate lights…

Any recommendations would be greatly appreciated!

 

By ACC, do you mean with the ignition in RUN?

Your choices are limited aft of the engine firewall. You'd have to tap into either lights, engine managment or alternator circuits. Possibly some roof circuits on the Spider.

 

Thanks for reply! Yes, I mean with ignition in RUN. I have 2000 standard Modena, so roof circuits aren’t there, and F1 circuits aren’t there. Lights are only on when headlights/parking lights on, correct? The secondary air blower on the left usually only gets power for the 1st 30 sec after ignition… the trunk latch switch only registered 0.04 V…

Would prefer to not have to turn on headlights to get the camera to work, but if there is nothing else easily accessible then I guess that is what I’ll do

 

Correct. I recall that some types of rear cameras need a constant supply or take a long time to power up (so you may not be able to wire them into your reversing lights).
I don't believe the US 360 has any provisional rear fog lighting which you may have been able to tap into (and have it wired up to an ignition source at the fuse panel).

Now that you mention the secondary air system, the secondary air solenoid valve gets permanent* 12 volts power a few seconds after the ignition gets turned on (i.e. after the RH engine ECU has run through its power up tests). The wiring at the solenoid valve is probably fairly exposed (not wrapped up in thick plastic), so you could put a splice there.
Note that there are a lot engine management components powered by this power source, so adding a camera probably wouldn't bother the engine management system from a current draw aspect. However, if the camera shorted internally, that would be another matter. For reference, these engine management components are powered by fuse 38 and relay 55 (RH Motronics Master) behind the RH seat.

Sorry, I haven't read the documentation for your camera.

*the voltage at the solenoid valve is permanent, but the earth required to activate the valve is provided by the Motronic ECU and is probably triggered by coolant temperature and other factors.

Are you fitting this as a reversing camera ? If so just tap into the reversing light power line.

 

Greatly appreciate the detailed reply! There appears to be a solenoid attached to the vacuum system in the right hand well behind the tail lights… would you be able to tell me if it has permanent power, and your opinion on tapping into this? Thanks!

Assuming that is for the RH exhaust bypass valve, that also has the same power source as the other valve. So, yes, it could be used. The violet wire is also the power wire (yellow/blue the earth signal from the ECU). I didn't realise it would have a rubber boot on it, restricting access. however.

Does the camera have a rechargeable battery inside? I would be hesitant to use engine management wires like these if it did.

 

I dont think that is the RH exhaust bypass valve as it is connected to the vacuum system tank but perhaps Im wrong…. But point taken regarding using anything in the engine management system. Appreciate the input and ideas.

So, I went with the path of least resistance and used the license plate light…. This way no wire splicing was needed as I soldered a wire to the contact plates. This means that I must turn on parking lights / headlights for the camera to power up, but it appears to do so quickly.

Also this made the install very compact clean and everything could be zip tied to the hood latch support easily.

It's not the RH exhaust bypass valve, it's the RH exhaust bypass solenoid valve. The exhaust bypass valves are opened/closed using vacuum from the vacuum tank. The vacuum to the bypass valves is controlled by solenoid valves.

Thanks for the feedback. Good to know this system powers up quickly. The reversing light wires probably could have been used, but the wiring would have been longer/messier.
