I just bought a Greddy turbo timer with harness plug for my WRX. I want to try and install it myself, and my question was is there somewhere that I can find step by step instructions on how to install it. I am not very good with the electrical system of a car, but I am great in any other category, anyway I don't have a lot of experience with wiring but I am sure I can figure it out. Do you think I should go ahead and do it or should I let someone else do it. can it be done is less than an hour? Thanks for your help.

 

I installed my HKS turbo timer myself with very little wiring experience (of course I used the wiring harness as well). With the harness and considering you have no experience doing this I would give you about 2 hours. Everything is relatively easy to get to. If you need instructions I would suggest using a search engine on the net. That's what I did.
