Default TB bypass help lol

Hey guys, its a rainy day so I thought I'd free up some power with the TB bypass mod.

I understand its relatively simple, but I got stuck.

I have a 95, after research our outlet hose is on the top passenger side of the TB, not the bottom like other models?

I'm following this picture;



BUT, I have this;



Theres supposed to be that metal line I bypass with, however I have that hose all the way back to the passenger valve cover, am I just being dumb?

you have to disconnect the hose on the bottom left of the tb, then take the hose running from the radiator that goes into the right side of the tb and just connect them. bypassing the tb. the hose you are looking for is comming off a tube running parralel to the fule rail. hope that kinda helps

Look on the left bottom side of the TB there should be a coolant hose running to it and on the right bottom side there should be another coolant line just disconnect them from the TB and connect the two coolant lines together and there ya go. Its very simple, you can find some thing to plug up the TB holes or just leave them open i just left mine open

one of the nipples on the bottom of the tb plates points pretty much straight down on the passanger side, the other is kicked off to the side pointing towards the front driver's side corner of the car. this is all going off memory though so I could be wrong.

pretty much best way to do it is to look for hoses on the bottom plate of the tb held on with clamps, if you pull it off and coolant/water comes out you picked a winner.

to connect them together go to Home Depot, Lowe's, whatever, and find a barbed male/male fitting that is the same diameter as the inlet of the hoses

Like 5 hp maybe, it makes sense tho the tb will stay cooler with out all the hott water flowing thru it.

I don't really even know if it adds hp, the best benefit to me was making removing the tb or intake alot easier and less messy

Are you guys absolutely sure?

I was going off this link, and it sure looks like it came from the top.

http://www.bfranker.badz28.com/fbody/intakefix.htm

read all the yellow text, the picture, which I linked should be the right hose, which is on the top of the TB, not bottom...

EDIT:
Gah I'm being stupid, I see it now...little bugger, what about the one that runs into the valve cover?
Thats a coolant hose too right?
