i have a y7 block and it is going to get the exospeed z6 stage 2 head and i will be using the z6 intake mani to. i was thinking of just using the a6 wire harness and then wiring in the v-tec,using a odb0 to 1 jumper with the p28 ecu. or i was going to stay odb0 and get a APEXi VAFC and just use that to activate v-tec. but i found a y8 harness on ebay very cheap and i was wondering if it will work for all the sensors and what not. or if any body has any other ideas for my set up?
