I'm in the middle of restoring a 1991 TVR S3, and need to replace the headlights. The old PVC wire needs to be stripped quite far back, and because I would prefer to use modern connectors (the headlight loom needs to be detachable because the headlights are attached to the bonnet) I'd like to butt splice thin wall onto the old PVC wiring, and then run the thin wall into the connectors.
Is this sensible? I would use heat shrink butt splice connectors to connect the old 14/0.3 (8.5 amp) PVC cable to thin wall 16/0.2 (11 amp), and 28/0.3 PVC (17.5 amp) to 28/0.3 thin wall (25 amp).
