Review: Miata NB1 to NB2 Headlight Conversion - I did a headlight conversion from a Mazda Miata NB1 to NB2 and used this wiring harness. The NB1 Miata has a ground switching circuit, so the diode in the harness needs to be removed. Once that's done, the low beams stay on when I turn on the high beams. The indicator on the dash also works. I wouldn't say this is super amazing quality, but it gets the job done and has been working so far, so I recommend the product!
Review: Works great - Does what it's supposed to do, fits right out of the box. Added bonus: Leaves low-beam on when switching to high beam... (Did not know this when purchasing so it made testing what plug was what (low/high) a bit interesting to say the least)... Note: It's fitted with four (4) 9006 plugs. So if you want to use the "official" high-beam-bulb (9005) you have to change out 2 plugs. None of the 4 plugs are marked to show what they are supposed to be (low/high). 9006 = Low beam (usually 55 W) 9005 = High beam (usually 65 W)

## Features

- One relay wiring harness set includes two 4-pin SPST relay module boxes, in-line safety fuse box, input +/- terminals, and H4/HB2/9003 input trigger and four 9006/HB4/9005/HB3 outputs for reliable and efficient electrical connections
- The pre-wired dual SPST 4-pin electrical relay unit, complete with socket and rated at 12V DC with a maximum of 30-40AMP, is ideal for most heavy duty electronic devices, light applications between 9-16V DC, with a wattage not exceeding 320W
- H4/9003/HB2 inptut trigger, with four sets of HB4/HB3 outputs, good for light applications with socket sizes of 9006/9012/HB4, 9005/HB3 H10 9145 9140 9055, etc
- Perfect for power management, this relay harness is ideal for applications like front fog/driving lights and off-road lightbars, pod lamps drawing power directly from the battery to prevent excessive load on the vehicle's existing wiring system and ensuring safe, easy on/off operation
- Installation tips: connect output contacts to up to 4 light applications/devices, attach red/black O-ring/C-ring to battery +/- or ACC/accessory 12V+/ground, connect the signal triggering wires to existing/factory adapter to trigger the on/off operation

### ⭐⭐⭐⭐ Does the job with a tweak.
*by N***L on January 3, 2023*

Converting my NB1 Mazda Miata to NB2 head lights. Wire lengths were perfect for this application. Had high and low beams always on until I cut diode out of the harness where it plugs into the stock head light plug. I think this is because the miata had a common voltage and switched ground, but I'm not sure. Lows stay on with high beam, but high beams cut off when switched to low. I don't seem to have a high beam indicator on my dash. I'll keep tweaking it to see if I can get that to work.
