Hi There
I'm a new member and could use some help.
I'm installing a Lowrance HDS 7 and a Navman 3100 fuel monitoring system via NMEA 0187 and need help with the wiring. The following are the wires for each device.
Which wires connect to which for a GPS signal for the Navman fuel motering system ??

RR, Unfortunately there is no wire color standard for NMEA 0183. You need to determine from the manuals which pair of 0183 wires on the GPS is Output or TX -- generally called + and -, but sometimes A and B -- and which pair on the fuel system is Input or RX. TX+ to RX+ and TX- to RX- should get the data flowing, and it's very unlikely you'll hurt anything by trying.
