The module you mention is merely to modulate the oil ground circuit to a square wave...beep, beep, beep. You don't need it as some engines in a year model, hp series, don't have the module....low end price wise. Tan and tan with light blue stripe are your fail wires. They send a ground to the low side of your alarm when a fail occurs. Without a module, just tie all those wires together and if you have a fail, you just get a solid beep and you have to investigate as to which it is. No biggie. HTH.
