I bought a Team SCSS gauge pod package.
Gauge pod and guages supplied by Team SCSS.
Wire harness and electronic oil pressure sending unit also suppied by Team SCSS.
1/8-28 ANPT thread tap and driver. Home Depot
25/32 drill bit. I used a smaller pilot bit and punch first. Home Depot
10mm wrench or small socket wrench to remove the nuts to access the plate for the oil sender. Home Depot
Small falt head screwdriver to pop the stock plate out. Mayer, Home Depot
I took JHP advice and put several layers of painters tape on the facia plate.
Instructions for the JHP install at the bottom of that page.
I used a "Dremel" to remove the material as required under the plate. Team SCSS suggest air tool and some other things. I have a dremel... Wal Mart
I bought a roll of wire wrap/loom. Autozone or any auto store
I supplied small black wire ties...had on hand. Oak Mountain Hobby Shop.
(I am into RC planes and heli's too)
Used an existing hole through the firewall with an extra hole impession. Same grommet the hood release cable exits through. Use an exacto knife to cut a small slit in the extra hole in that gromment. Team SCSS explains this with the instructions they include.
JHP looks easier and very nice. I just wanted the 1/2 step increment full sweep gauges and I liked the Team SCSS pod design.
That and JHP is $595.00 US Dollars shipped.
Team SCSS $429.00 and $15.00 S&H.
For MY 2004 model GTO. JHP is cheaper for 2005-2006 fly by wire GTO's.
For all year GTO owners there are several options for adding gauges.
, Maryland Speed
for SCSS also.
Probably more option out there
For an "A" pillar install.
I know there are more options to install on the A pillar.
Browse here first.
Lots of info right here in the gtoforum, interior thread.
For my head, real time oil pressure monitoring is a must.
I am not suggesting or knocking anyone's product. Just a look at my choice.
Hope this helps someone.
