1994 855. My gauges setup.

I wanted to put in a wideband and boost gauge before I start changing things in the M4.3 ECU, and eventually put a M4.4 in my 94. I didn't like the A pillar setup and I need my vents to be working.

I bought a tray from Volvo and modified to work with the gauges. Aftermarket tray opening is small, get a tray from Volvo Dealer only, part # 9132775 black. I'll let the picture speak for itself.

Boost gauge is mechanical, water gauge is electronical.

Radio harness supplied ignition on to drive a relay, also the dim lighting for the lights, since my radio doesn't use that wire. Everything is grounded to the battery, and I found a constant 12+ under the dash.
