INSTALLATION INSTRUCTIONS

IMPORTANT

1-1/2" ELECTRIC MINI GAUGES

Instr. No. 2650-235D

Congratulations! You have purchased a quality
gauge that will help you monitor your vehicle's vital
functions. 18-gage wire is required for installation
and can be purchased separately at an auto parts
store near you. Auto Meter wire kit no. 2214 is
recommended.

Preliminary Steps

1. Read instructions thoroughly. Please consult a qualified mechanic if
you have not had training in the proper installation of instruments.

2. Determine ideal mounting location. Choose a location that will not
obstruct visibility or impair driving. Consult your vehicle's repair manual
to locate:
A) water temperature port
B) 12V ignition switch or fuse box
C) oil pressure port

3. Consult your vehicle's manual to determine the best route for tubing to
follow. Choose a path free from hazard of moving parts or hot engine
components.

4. Assemble tools and parts required for installation.

5. Disconnect negative (-) battery cable. Do not allow terminal to touch
battery or any metal. (NOTE: Disconnecting battery ground may require
you to re-program your radio station and clock after re-connection.

6. Hold console in desired mounting location and use as a template to
mark drill holes on underside of dash.

7. Drill holes with an 1/8" drill bit and mount bracket under dash using
self-tapping screws and flat washers provided. Mount console to
bracket by lining up side holes of bracket with side holes in console. Fit
8-32x1/2" screws and no. 8 flat washers provided through side holes in
bracket and console. Screw into nut attached to inside of panel.

CAUTION: Some late model vehicles use electronic sensors in their

pressure and temperature senders for engine control functions. Before
removing the original senders, we recommend that you contact your
automotive dealer to be sure no critical functions will be disrupted.

■ With pressure gauges, it is beneficial to add a T-fitting to install your
new gauge and to keep the warning light operational. This allows you
to monitor the pressure and still have a warning light to indicate
emergency conditions.

NOTE: For light bulb replacement order Auto gage no. 2388.

Important Assembly Procedures To Follow

Tighten nuts and lock washer that secure the gauge mounting bracket.
Be sure they are not so tight as to bend or distort mounting bracket.

Install additional wiring and hardware as shown in diagrams below.
Now tighten the outer nut while holding the inner nut. This is the only
correct procedure and must be followed to insure safe electrical
connections. This applies to the gauge and both senders.

Make sure wires are not rubbing against metal or each other.

1. Drill a 3/8" dia. hole in firewall. Install rubber grommet provided in
firewall to insulate wire where it passes through sheet metal.

2. Remove existing oil pressure sender. (For computerized vehicles see
caution in Preliminary Steps.) Install new Pressure Sender using
sealing compound on pipe threads.

3. Cut three lengths of 18-gage wire. Strip insulation back 1/4" on each
end of wire and attach solder lug terminals to each end.

4. Connect one end of wire with solder lug terminal to sender (S) terminal
post on back of gauge using split lockwasher and nut provided. Route
wire through firewall. Connect opposite end of wire with solder lug
terminal to pressure sender using split lockwasher and nut provided.
