he is probably telling you that cause he wants you to buy their $100 remote cord. i literally soldered a radio shack momentary to a little extra wire then to the relay. then just wrapped the slack of the extra wire with electrical tape and bam, cheapo NOS cord
He cleared up the confusion thru another email. He said it wouldn't be a problem, u just can't have both the boost activation switch/tps switch AND a manual pushbutton switch. Either one or the other, which was what I was asking.
