hey guys tryin to hook up a turbo timer but am unsure where to hook the ignition wire to I only have a humble test lamp and trial fitted the wire to a wire near the barrell which had power only when ignition was on, the car remained running after I took the keys out but did not time out, I dont want to keep hit and miss trying diffferent wires, any help would be appreciated also I have a boost gauge I wish to install but have had differing opinions on where to connect the line. any help would be appreciated cheers
