Disconnect one side and check the other side. Do same for other side. Determine if one of the lights could be faulty.

The ‘Bulb Check’ circuit used for Engine Coolant. Without gauge (bulb only), the bulb will light when engine is in CRANK, with gauge, gauge will peg (HOT) when engine is in CRANK.

Its kindness when you help an idiot out. Now I understand. Thanks for the insight.

I have to ask, since I don't know, but what does RP, RD, FP and FD mean?

Sounds like the HORN wire. Correct color code for wire.

Eliminate the Fuel Pump Ballast Resistor as being your problem. Bypass it.

Not sure on protocol, but Nick can talk to ECU. Renix Engine Monitor

Small mention for the CC, at the end. MATTEL CREATIONS FORUM

When the tip of the rotor and the tower terminal (cap) are not lined up properly (indexing), sometimes caused by dropping in the Distributor one tooth off. At higher RPM’s when vehicle is calling for MAX advance (timing), rotor will crossfire to the wrong tower terminal. Carbon build up in the Distributor Cap can also cause crossfire.

The reason I asked is symptom sounds like/could be crossfire in distributor cap.

The ECU connector(s) would never allow swapping the 2.5L (C200) with a 4.0L (C201 & C202) ECU.

Did you do Distributor Indexing?

Go Blue!

Check wire for continuity between terminal 85 (Fuel Pump Relay) and C200_6 (ECU).

Yes.

During Engine CRANK, look for battery voltage on D1_4. (Start Signal (+)) I believe it to be a 5vdc square wave, requiring an oscilloscope (high impedance device) for measuring.

True, I've seen songs with the same title but with different artists, play back-to-back, in a row.

Shuffle I'm up to 900 songs now and still growing. I call it MyMusic. Two sticks, one for my ride, the other for my TV.

Not sure here but try this. KEY OFF With brake switch ON (depressed), can you, using the TS switch, turn OFF the Right Taillight? Same for the Left Taillight, can you turn it OFF using the TS switch? Each one separately.

Good question. Euramtecs schematic

Correct.

Euramtecs switch function is different than the factory swtich. Minor but different. Factory switch is (Switched-OFF-ON). Euramtecs switch is (ON-AUTO(Switched)-ON)).
