Some people use the brake booster hose. I've had good results using the vacume tree over by the pcm and heater box.

I "T" into the vacuum line right before the check valve line at the back of the manifold. It's a little bit of a pain to run it like that but you get a very strong signal. If you follow the brake booster line to the back of the manifold there is the factory port into the manifold. The drivers side feeds the large brake booster and the passenger of the port goes to the check valve. That's the spot I'm talking about.
