Hi, I'm currently updating my headlights on a 1970 HG Prem wagon and need to locate the Relay so I can update the capacity. Current wiring diagrams uploaded on this site haven't included the relay so any help would be appreciated. Cheers Phil
It may not have them, you might need to wire them in. My memory is that its wired straight from the switch to the lights via the fuse.
Happy to be proved wrong but remember a mate having to fit high and low beam relays to put HZ halogens in his HK

My HJ prem never had them stander, my old man changed the inside spotlight for those spot landing lights and added relays, 120w and “back in the day” they were bright lol
So yea HK-HZ I don’t think they had them, even the statesman

no headlamp relay as standard on those. If you upgrade power then put one in and make sure the wire gauge to the lights is well rated for the current ..Current (Amps) = Power (Watts) divided by Volts (12V)...go for something with a decent margin to allow for any volt drop over longer wires..

No relay on HG
HG has no relay for the headlights.
If upgrading to Halogen no need for a relay as lights take same current. HZ have halogebn and also no relay.
Not sure which GMH car had a relay for the lights first but it would not be until the 80s.
head light relay's
I don't think any early holdens had head light relays untill commodores .
you can buy headlight relay kits
