Replacing Volvo gauges on 1985 MT Labelle
We are trying to replace Volvo gauges on our 1985 Marine Trader Labelle. We purchased Sierra gauges as replacements. Our first problem is that the existing gauges are connected with slide-on, "plug" type fittings. The new gauges need ring terminals which, it seems, can be crimped onto the existing wiring and then attached to the new gauges.
How do we determine what size ring terminals to get? Do they need to be purchased both by ring size and wire gauge? And do the ring / wire sizes generally vary among instruments or does "one size fit all"?
Thanks.
