there should be installation guide provided along with ur unit... as for where to connect the vacuum hose, find a vacuum hose which comes out from ur intake manifold... use a T-joint and tap from there...

Hi,

This should be a simple job, kindly open up your engine hood n start searching for the vacuum hose.. when u ram (press the fuel) u will the suction of the hose.. cut in the middle of the host and joint it with a t-socket 1st & 2nd joint to the actual vacuum hose & the 3rd joint it to your vacuum gauge. For your vaccum gauge u can juz simply tap the power (+) from any source e.g. fuse, lighter socket etc... the negative (-) terminal u can tap to your car body or earth or any nagative source.. done.. now when u ram (press the fuel) u will see the gauge meter moving and the light is on..

**note:- if u tap to ur car lighter power, your gauge will on when ever u start the engine.
- if u tap to battery terminal u better add in a fuse and switch.
- if u tap to fuse (e.g. small light power) then your gauge will function when u
switch on ur small light
