First off I do have a TC and I know this is the Xb fourm but I know you XB's bagged your ride all the time. Im having trouble with adding compressor 2 relay. I am just making sure I am doing it right and wont blow up anything lol.



In pic number one for the single compressor this was already pre-wired

#30 on relay goes to battery or a power source
#86 goes to my ECU "I think is +12)
#87 goes to compressor
#85 goes to ECU "I think is ground) NOW



Now In pic two to add compressor #2 THIS is where I am lost

It shows #30 on both relays now run to the compressor IS THAT RIGHT???
And shows #87 is now "+12v battery or a power source" for both relays IS THAT RIGHT????
I think #85 is the same just jumped over
and #86 on relay 1 stays the same

Just having trouble with wiring the compressor and battery

 

that how it set up like the pic says
