Wiring harness from hard top to the car loom, Mazda MX-5 mk1 1.6. This is the TWR type with the round 4-pin plug on the right hand side of the car.
It was only on very early UK cars with the TWR hardtop, distinguished by having an interior light and a heated rear window, the wiring plug is on the r/h side.
This loom plugs into the existing wiring in the car and has it's own fuse box for the interior light and HRW.
It does not include the HRW switch.
