3.0 Vacuum Diagram anybody

I have a 90 3.0 and the throttle body has only three vacuum lines on top and no diaphram at the TPS like the 95 does. The 95 is like new and would like to use it
but can't find a good layout of the vacuum lines for it. It's like three more lines coming out of the new one. I have done a search but no luck.
Thanks
Roger

that's a good one for the 90 model but the 95 is the one i needs.

Thanks

Could you take a couple of different angle pic's of both TB's side by side?. Something just seems weird. I'm pretty sure that the motor was changed from a 3.0 (3vze) to a 3.4 (5vz-fe) in mid 95.

EDIT: After some thought I'm thinking it's probably different because of manual or automatic transmission and if it has cruise control or not.

He's asking if he can use the 95 throttle body assembly as he states it's newer.

I just did the same to my 90 runner since the idle air valve was shot. It will work as long as you hook the right lines up where the old ones hooked up and you may have to plug off an extra port if not already done
