H4 wiring harness upgrade

Just so you know, so you don't have to run all over the place getting bits and pieces, Ashdown-Ingram stocks all the auto electrical parts you'll need. There's 8 branches in Vic listed here.

Use a resistor relay instead of the diode relay too. Less chance of it blowing

Thanks. The reason I prefer diode relays is because they clamp the back-emf voltage spikes from the relay coil to zero, whereas resistor relays just reduce it. They are both safe for car electronics, it's just that one's a bit safer. And what do you know, Ashdown-Ingram have got a site in Hobart, too, in the old Philips warehouse. I'll have to go and check them out - it's only a 5 minute drive away, or a 30 minute walk.
