This would be true if the low / high beam wattage is the same as what you have now.. If you intend on putting brighter [higher Wattage] bulbs then the current draw will be higher. P = V I where P = watts V = volts and I = current.

Power, Volts and Current

Re the QH upgrade. I went along to repco and the quote for the kit was $160, none in stock.
Then I went to super cheap $12 each for the semi sealed lamps and then anwhere from $10 for the stocko bulbs to about $27 for the fancy pants bulbs in glossy boxes.
Any suggestions on which way to go and what the pitfalls are ?
The guys at the two shops said that there was no need to change any wiring as the existing bulbs are high, low beam (three pin connection) and drawing the same current.

Dodgeman, I option is to head to pick n payless ( or another friendly wrecker with an N13 ) and strip their wiring to track what you need.

If your local auto sparks didn't recomend a QH upgrade then he isn't doing either you or his business any favours. It's not horribly expensive or difficult to do yourself & a competent auto electrician should be able to do it in an hour or so if he has all the bits on hand.

DIY is more satisfying & economical.

That's the way I have done it for many years on quite a number of cars [without the ignition-on feature, & thanks for the tip] but this time I thought I would see how hard to make it look more 'factory' & at the same time incorporate some extra features with the extra relays while utilising low cost, but 'genuine' relays from wrecking yard donors.

What you saw in the pictures cost me $20 while two new aftermarket relays alone were priced at about $28.
Yeah, I know, Im a bloody perfectionist, a glutton for punishment & a damn cheapskate. Guilty as charged.

head to repco and buy a pair of headlights that take the h4 halogen inserts, grab some bulbs while you are there.
whack em in your car and wire em up with a relay and power from the battery.

Hey guys, What is the h 4 conversion you are talking about? I've got a 120y and the headlights are so poor its not funny. I've been to the auto electrician with no joy. The low beam is what I'm really worried about.

I have found that older EA-EB model falcons ahve a row of relay blocks which you can strip the old wiring out of and purchase some new 'pins' and rewire anyway you want. I have done this in my Cedric wagon and the deceased datto 1000 wagon and my Escort Panelvan for both headlight upgrades and fitting spotlights and the starter realay too! The blocks slide together and can then be mounted under the bonnet neatly. Plus your using new wire so no worries about it not being up to speed or having internal faults!

seems like overkill, i hacked in relays by making a harness that plugged into one of the headlamp sockets in the oem harness, that controlled the relays which were under the hood it works nicely and allows you to hook up the headlamps in such a way that they never can be on if the key is off. why arent all cars wired so the headlamps are off when the key is off, some are, subarus for one...

I would say go for under bonnet, easier for install. Just on the inner guard near battery. Go for that factory look, as well as most of the late model nissans use the same colour coded relays. No thinking required, just plug and play.

You could go for head light relay [given] , horn and starter. and have the spare relay sockets for the "NOS" controller and supercharger electric clutch pulley.

That would have been the easy way out though!

I just threw a H4 conversion in the 1000 with +25 globes and all good, heaps of light and no frying.

Have fun with the N13 stuff
