Auto Electrician Needed Today – Wire Exhaust Valve Controller on m340

$80

Ryde NSW, Australia

21st Oct 2026

I have a 2019 BMW M340i with an aftermarket valved exhaust already installed mechanically. I need someone experienced with automotive 12V wiring to connect and power the exhaust valve controller. The exhaust comes with its own valve motors, wiring harness, controller and remotes. The job should mainly involve: * Connecting the controller to a proper fused 12V power source * Grounding it correctly * Connecting/routing the wiring to both exhaust valve motors * Testing that the remote opens and closes the valves properly * Keeping the wiring neat and secure No exhaust fabrication or mechanical installation is required. Location: Ryde / nearby Sydney area. Looking to have this done today if possible. Alternatively book me in somewhere and confirm they are able to do it same day or asap and I’ll pay you 30 for that. Please only offer if you’re comfortable with aftermarket automotive accessory wiring and can complete the job safely.

Looking for an auto electrician to help cable up the lights on canopy.

$200

Edgeworth NSW 2285, Australia

2nd Aug 2026

Auto Electrician Needed – Install Rear Canopy Lights & Check DC-DC Charger Wiring I've recently fitted a new tradesman 4x4 canopy to MR Triton and need the rear LED lights wired up and installed. It looks like a fairly straightforward job, but I'd prefer someone experienced to do it properly. Manual says like hour jib so sure you could smash it out quickly While you're here, I'd also like you to have a look at the wiring for my DC-DC charger. It stopped charging the auxiliary battery after I changed the Anderson plug, so I'm guessing I've done something wrong and would appreciate someone diagnosing and fixing it. Looking for someone with auto electrical experience who has their own tools. Located at Edgeworth Please let me know your experience, availability, and quote. Thanks! 🚙🔧

I have a 1991 landcruiser 80 series, when I plug a charger in the lighter socket it trips the radio and clock that are directly above it on the dash and all three don't work. When there is no charger plugged into the lighter socket the radio and clock work fine. I assume there is a short behind the dash so would like someone to fix it.

Excellent work very happy! Will definitely use again
