Installed dual aerforce interceptor gauges via obd2 port and they worked well for two weeks.
Decided to add oil temp and oil pressure sensors to analog 1 &2 on one of the gauges.
Added sensors via T in accessory port in oil housing. Ran wiring into passenger comparment.
Both sensors are wired with 5V regulators as recommended, also used "4A add a circuit" from aeroforce through left and right low beam headling fuses (10A). Grounds from both sensors were spliced and added via stake on / bolt to sheet metal housing holding fuse box, tight with good contact.
Turn car on, gauge with out sensors is fine, gauge with sensors has a black screen and redlights blink randomly on and off.
Disconnected fuses, unpluged and plugged OBD2 port, no change.
Even with fuses disconnected (no power to sensors) won't go into standard OBD2 reading.
Any ideas?
thanks in advance
