help me with this

[ooraceredgt]

i just put in a 2001 engine in my 2000 mustang and i ran a diagnostics on it and came up with 2 codes.

1. cam positioning sensor
2. lack of ho2512 switch

the positioning sensor is self explanatory but what the hell is the ho2512 switch. if anyone could give me some insight on this it would be great. also ford warranties suck thanks
