Help need for head circuit ,possible and for other
My friend have a modified rx7 fd with 20b moter on.
The control for the engine is made from microtech ecu and harness so the fd engine harness is complete out.
Because and the main harness is usefull only for starter,head lights,wiper,flash,horn,we decide to take out and this harness and make new little harness to control all this.
My question is about the head circuit, as I can see in the service manual page (z54 ,page 57 acrobat) it use 30ampere fuse then go to relay and then into combination switch and after that direct to the bulbs.
It is possible the combination switch to handle 10 ampere for both bulbs?
It is better to install 2 relay after the switch one for low beam and one for high?Or there is no reason to do this?

-Yes, Petros. I don't know what Mazda's engineers were thinking, but the RX-7 does not use a headlight relay; power goes through a fuse, through the headlight switch, and directly to the headlights.
If you plan to install higher-wattage headlight bulbs, I would recommend installing a relay. A shorter wiring path should increase the brightness of the factory headlight bulbs also. If you don't plan to modify the headlight bulbs, the factory setup should be sufficient. The wiring is pretty large, maybe 16-18 gauge.
