These SMART modules by JTX don’t just do canbus but also fix negative or earth switching issues.
To eliminate confusion we set out to make these as fool proof as possible. Simply plug these into the old headlight sockets.
These now fix all of the following …
- Negative or Earth switching which all toyotas have
- Reverse polarity issues
- Blue hi-beam dash light
- Spotties not coming on in high beam
- Some cars have computers polling to test loads and these satisfy those computers too.
No matter what brand of LED or even HID you are trying to use, if you have a Toyota, Suzuki or old Datsun then you do need these. Every Toyota known to man (even yours) came out with negative switching and even today the new models still have it.
You need 1 module per light. This listing is for 2 modules. If you have 4 lights you will need a second set.
If you are running DRL Halo those need an earth and some cars (not all) have no earth to the inner high beam lights unless they are turned on. That means the Halo will struggle so the trick is to join the earth wire at the inner light to the earth wire of the outer light.
JTX also sell Superlooms that address all of the above as well – in fact the superlooms offer new earth to the lights and operate them like a conventional car would so there is no issues with the inner DRL not working. Here are the links to the 2 JTX Superloom options….
- 2Way Superloom (does 2 x lights) …. https://www.jtxlighting.com/product/led-wiring-kit/
- 4Way Superloom (does 4 x lights) …. https://www.jtxlighting.com/product/led-super-loom/
Note a select few cars need a superloom as well as the JTX Load module and whan that happens JTX are there to help you out – please be sure to fit the JTX Load Module to the old factory headlight sockets and not between the harness and the lights. Otherwise the car wont know they are there.

I didn’t wind up using the modules, as I had already made my own, but they would certainly make retrofitting a breeze.
