Make sure they're high-quality, robust relays.Make sure you're not trying to use two speeds. The Sniper is designed to work with two fans, not two speeds. That can create issues. Simply use the high speed and you will be fine.Also, remember that the Sniper provides a GROUND. It does NOT output +12VDC. You need +12VDC coming from elsewhere (I just jumper a small wire from Pin 30 to Pin 86 since I already have +12VDC going into 30).Yes, like said here, route your wires as far away from high voltage plug wires, etc. Make sure you're using resister-type plugs. I bought ferrite beads cheap on Amazon and threw them on everywhere.<a href="https://www.sn95forums.com/threads/my-351w-swapped-1995-mustang-gt.75574/" target="_blank">Here's my build thread for my car</a>, I have a Sniper EFI and have had it for a couple years now.BEFORE you run this car, remove the two side covers and zip tie your injector plugs down to the injector (<a href="https://www.sn95forums.com/threads/my-351w-swapped-1995-mustang-gt.75574/post-1485135" target="_blank">link to my build thread post with photo</a>). These are a known issue and something I discovered on the dyno with my new 427w. Thankfully, we noticed there was something funky going on before we hurt anything.</blockquote>
