Infiniti i35 wiring diagram

Question edited for clarity and toss in some CAPS.

There is nothing that backs up memory. When you disconnect the battery, all memory is lost, which is why it is important not to do it!

You don't tell us the model? Is it a secret? All questions need 'year make model' as the FIRST 3 words.

If your have a 1999 Infinity I30, the ECM Fuse is Fuse 58.

NOT TOLD THIS.
DOES CAR DRIVE AND RUN OK DAY OR NIGHT, GEE NOT TOLD.
KEY OFF HEADLAMPS ARE BRIGHT.?
ALL FUSES TEST GOOD.?
SCAN THE CAR (PCM) YET. OOPS IT TELLS YOU WHAT IS WRONG.

MOST MODERN CARS THE BCM RUNS LIGHTS. ALL OF THEM AND MORE
the only easy cure is remove the battery neg lug off battery and wait 1/2hour and put it back hoping the BCM wakes up.
or the brake switch is bad.
scanning finds is , why wait to scan it?
many places do it for free. or buy the tool and uses it.

Here is the diagram and very often there is a diagram on the fuse box lid.

The fuse box is located behind the cover to the left of the steering wheel. The location of the fuses in the passenger compartment: Infiniti i30, i35 (1998.

I don't know if this could help you or not but I have a 2004 Infiniti G35 sedan and my brakes lights went out and I couldn't figure it out and I'll be damned if it wasn't in the wiring harness that comes down when the trunk closes there's a little one to the right there and I don't have a 2004 but don't count that one out you have to split it and you'll see that the wires somehow just got dry and cut from the sleeve and I just rewired it boom back together and it runs and it stops with brakes lights anyways good luck.

Check the display. Ask a helper to step on the brake pedal while you check the lights from the rear. If no lights appear, check the fuse that connects the brake lights. The owners manual will show the location of the fuse box and which fuse is for the brake lights. Pull out the fuse and look at the wire in the central window. If the wire is broken, replace the fuse. Make sure the new fuse is not blown, and carries the same amperage.
Take note of lights that are out, if any are working. The problem may be cured by replacing the bulb in a brake light that's out. A burned out bulb has a broken filament and a dark brown spot on one side. Check the owners manual for bulb type.
Check the circuit if replacement bulbs and fuses do not restore the lights. Find the wiring diagram in the vehicle assembly manual. The circuit for the brake lights runs from the battery to the fuse, to the pedal switch, to a connection plug, to the lights. The circuit has to be checked with a volt tester at all points.
Check the battery power and the light on your volt tester. Turn the ignition key far enough to activate the electrical systems. Turn on the lights to check for battery power. If the battery has power, ues it to check the volt tester. Put the black lead (the ground) from the volt tester on the negative battery terminal. Briefly touch the red tester light on the positive terminal. The light on the volt tester should flash brightly.
Test the wiring to the fuse. Clip the ground wire to solid metal near the fuse. Touch the light tip to both sides of the fuse. Both should light the tester. If neither side lights, the wire between the battery and fuse is bad. If only one side lights, the fuse is blown.
Test the switch and wiring. Touch the light tip of the tester to both terminals on the brake pedal switch without putting any pressure on the pedal. One should carry power and the other should not. When both show power, the switch is stuck and the brake lights are always on. If neither shows power, the wiring between the fuse and the switch is bad. Now check both switch terminals while the pedal is depressed. Both sides should light the tester. If not, the switch is bad.
Check the connection plug. Unplug the connection and refer to the vehicle manual to identify the brake light wire. Touch the tester light on the brake light wire at the inner socket on the battery side. If the tester lights, the power is flowing to this point. If not, the wire between the plug and the pedal switch is bad.
Check the socket. Plug in the connector plug and remove the bulb. Touch the contact inside the socket. If the tester lights, the socket is good. The socket and wire running to the plug should be replaced if the tester doesn't light.
Check the bulb with the ground wire. The bulb must be in its socket. The ground wire running to the socket should be black or brown. Stab the tester through the insulation. If the tester lights, the bulb is good. Replace the bulb if it doesn't light.
Check the ground wire. Remove some of the insulation around the ground wire. Twist one end of the extra wire around the exposed ground wire. Touch the other end to a solid piece of metal. If the brake light comes on, the ground wire is bad.

Need to find brake light fuse location. It isn't in the fusebox under the hood. I looked everywhere in the cabin except where it apparently is. The brake lights come on all the time and drain the battery.Even after changing the pedal pad and verifying the brake light switch plunger is all the way in the brake lights remain on. I need to pull the fuse so I can at least move the car and not have to leave the negative terminal disconnected.

As you have probably discovered, the diagram isn't included in the
Owner's Manual (http://www.downloadcarmanuals.com/1997-infiniti-i30-owners-manual-download) or even the service manual (Infiniti I30 and I35 Factory Service Manuals NICOclub).
It looks like the layout is the same as the Maxima from that era:



The 1998 layout is the same, although I'm not sure whether the actual lid/door will fit-

your power starts at the brake light fuse,check with a test light,then proceed to stop light switch on brake pedal under dash,one wire will be hot when when you check it with your test light, the other won't be until you press down the brake pedal then the power flows through to the second wire,if no power to second wire replace switch,if you have power remove tail light bulbs and check for power in side socket.

Doesn't sound like the brake lines were bled properly. Many times after pad and rotor installation if the lines are bled correctly you will have to pump them initially after the repair for a couple of minutes until the pressure is built back up. Also check the master cylinder and make sure fluid level is ok.
