Install Supplies & Wiring

Fuse taps, relays, harness tape, cable ties, switches and the small parts that make an install clean and reliable: the same supplies we use on our own installs at our Markham shop. Pick a job in the kit builder and it lists what you need, or shop by category. Flat $10 shipping in Canada, free on orders over $200.

Give every new power wire its own fuse

A fuse protects the wire, so every power wire you add needs one, rated no higher than the wire can carry. A fuse tap does it at the fuse box: the car's original fuse goes in one slot and your new circuit's fuse in the other. Not sure which tap your fuse box takes? Our fuse identifier shows each type at true size.

Use a relay for anything heavy

Remote starter and alarm outputs, and small toggle switches, are made to switch a little current. For lights, horns, fans and door locks, let them trigger a relay and let the relay carry the load. A relay harness turns a bare relay into a plug-in part with colour-coded leads.

Tape: fleece inside, PET cloth under the hood

Tesa 51608 fleece tape is what we wrap interior harnesses in: it tears by hand and stops rattles. Tesa 51036 PET cloth tape handles engine-bay heat and abrasion, and Tesa 51618 matches the factory tape on BMW and Mercedes. Keep electrical tape, like 3M Super 33+, for covering joints rather than wrapping looms.

Seal anything that goes outside

Pack DUM-DUM butyl round wires that pass through a grommet or a drilled hole, use a waterproof connector where a joint lives outside the cabin, and put anti-corrosion gel on connections that will see moisture.

Make it stay where you put it

Double-sided tape lets go of textured dash plastic on the first hot day unless you wipe the surface with 3M 4298 adhesion promoter first. Mount modules on hook and loop so they lift off for service, and tie new wiring to existing looms every few inches with cable ties.

Job kit builder

Pick the job and we'll list the supplies we'd use, all from this store. Untick what you already have, change quantities or fuse types, and add the rest to your cart in one go.

What's the job?

Hardwire a dash cam

Power a dash cam from the fuse box instead of the lighter socket, with the cable hidden behind the trim. These are the supplies around your camera's own hardwire cable.

You also need the hardwire cable made for your dash cam. It isn't in this list: find it on your camera's page or in Dash Camera Power Cables.

Rather we did it? Dash cam installation at our Markham shop, from: Front Dash Camera Installation $150 CAD

Add an accessory circuit

Give a 12 volt accessory its own fused circuit from the fuse box, with a switch if you want one. Anything drawing more than 12 amps should go through a relay: see Wire a relay.

Leave airbag, ABS and engine management fuses alone, and fit the fuse tap the right way round: the fuse tap page shows how to check.

Install supply questions

Which fuse tap do I need?

The one that matches the fuses in your fuse box: ATO/ATC, Mini, low-profile Mini, Micro2 or Micro3. Use our fuse identifier, or text us a photo of your fuse box and we'll tell you.

When do I need a relay?

When the load is bigger than the switch or module output feeding it. The remote starter output, alarm output or toggle switch triggers the relay, and the relay switches the heavy current. Our relay wiring diagrams show how to wire one.

Which tape should I wrap wiring in?

Inside the car, Tesa 51608 fleece tape: it tears by hand and stops rattles. Under the hood, Tesa 51036 PET cloth tape, which handles heat and abrasion. On BMW and Mercedes, Tesa 51618 matches the factory tape. Keep electrical tape, like 3M Super 33+, for covering joints.

Do you sell in bulk?

Some supplies come that way: our 4, 6 and 8 inch cable ties are 1000 packs, and ATC and ATM fuse taps come in 50 packs. For larger quantities, text or email us.

Can you install it for me?

Yes. We hardwire dash cams and install accessories, amplifiers, remote starters and alarms at our Markham shop, and every install is backed by our lifetime installation warranty. Book an installation.

Do you ship across Canada?

Yes. Shipping is a flat $10 on orders under $200, and free in Canada on orders over $200. We also ship to the US and worldwide; US orders may be charged duties at checkout.

Not sure what you need?

Tell us the job and the vehicle. We do this wiring every day, and we'd rather point you to the right part than have you order twice.
