I have to go to fed ex today to pick up my turbo timer, I ordered the HKS type 0 (because the type 1 was over a month out) and the matching timer harness for my 89 supra. Well what I was wondering is it just plug and play with the harness, or do I have to run any wiring to my ecu or anything else besides the E-brake ground? And if anyone has a how to or step by step for this please feel free to share with me. Thanks.
