Fortin EVO One Relay Wiring

Hi to all fellow members 🙂🙃🙂 I am looking to install a RS using FORTIN EVO ONE along with TB-VW to a 2012 Golf Wagon Std Key Manual Transmission but as i was checking the install guide i am very confused with how the relay was wired coz why do you have to cut the 12V supply, i know it needs a 12V then a neg trigger to make it work, but this one is new to me. Any help is much appreciated. Thanks in advance 🙂🙃🙂 ffg

you have to cut the 12v, so you can use the - negative park light output on the EVO-one to activate the Park lights. the relay is "making" the negative output on the evo into a positive park light output

Thanks for replying silvercivicsir. So relay pin 30 and 85 i will put jumper wire and has no connection to any wire, then it will work fine? Sorry am not good at this. Thank you againffg
