I just purchased a nuetral safty switch from IPD, it's located on top of the transmission left side. It is where the shift cable itself is connected. reports are that it is in a very hostile enviroment, under the battery, top of the trans and is subject to failure. I purchased it nd now I can't figure how to get thew male plug apart to change it with out destroying the plugs plastic cover. Stay tuned, but you may look there. Drifter
