I think you will find they are "common earth" blocks. There will be one wire coming out that is connected to the chassis.

Sorry guys for missing infos, it is a r33 dashboard wiring harness, the car is manual and I have 1 green, 1 black, 1 blue, 1 orange.

I have the green,black,blue close to the dashboard fuse box and the orange on passanger side close to the ecu.

I would like to know them cause a lot of wiring is going to finish at these connectors and I have discovered that most of wiring that is coming (or going) to the trunk ends (or start) at these connectors that is a dead end (or start) for the wirings.

I have disconnected the abs actuator and followed the wirings from ecu to the middle of my car. ( I have the wirings cutted at the front seats because of the wiring harness came from a 95 r33 front clip.)

And because I have a 90 r32gtst and my wirings form the seats back are r32 I'm having problems to find the wirings for: tailights,reverse lights, trunk lights, fuel pump, fpcm, interior lights, sunroof, seats, rear wiper, rear de-fogge, so any info about the wiring color codes that is coming from the front to the trunk will be really aprecciated.

I have found the rl/rr speakers, pw antena, ill., so anyhelp will be really welcome.

ps:I'll post pics of my r33/r32 (front end,motor and dashboard wiring harness)swap asp.

I had one in brown near my ECU with a heap of wires spliced and one near the Steering column, I'm quite cirtain they were for a non fiunctioning Alarm system that had been removed prior to me taking ownership.
