this is a new type of relay block with built in ( replaceable ) fuses

1 main power feed in ---- 2 -relay/fused power leads out , with trigger connectors

Dual 70 Amp Relay Board

they finally came out with a weather proof ( old ford style solenoid ) heavy duty relay

scroll down to the COLE / HERSEE section ( 6th one down on the left ( red one )

relays continuous duty 12 volt & 24 volt DC power relays,starter relays

i will be using only these relays from now on

way better quality than the small bosch type relays , and way easier to wire up several lights using eyelets

 

I used something simular when I did my efan install. I found that the custom rod parts sites have had this stuff for a long time. I guess these guys are always doing clean electrical installs!
