no crank, how do i bypass the system
 

i just finished putting my new harness in. now my car wounlt crank at all. it almost sounded like it did for a split second and now wounlt do anything when i turn the key.
i have done this on other vehicles but how would i do it on the 87 supra. running a jumper cable to the starter from a battery just to make sure the starter is still good and the car cranks, i would like to know if it runs or not.
i only see the one wire clip on the starter and the big power wire.
does anyone auctly understand what im tring to do?
thanks

Turn the key on and connect a wire to the - battery post and hit the post where the battery cable connects to the starter. I think thats where you hit it. I can't remember now. It's been so long since I've done something like this.
