    Turn signal fuse blows

    So I have my LS swap running, but I have a problem with the turn signal/back up light fuse. It works in key on position, but as soon as I turn the truck over to crank position to start it it blows the fuse. I have heard it can be multi-function switch ,but I would think it wouldn't work in key on position? I have looked for any shorts, but I have had no luck finding one under the dash or wiring up by the headlights.

    HELP!!!!!!

    do you have a neutral safety switch from a newer truck in there i be leave they rest at ground to send signal to the bcm to alow the truck to crank. Maybe the older truck use a positive signal straight from the neutral switch. just a thought
