Spliced wire. What to do? - ZR-1 Net Registry Forums

Billy Mild · 05-03-2016

In the process of taking my chip out of the ZR1 I noticed a spliced wire for the ECU wiring harness. Attached is a picture. What should I do to remedy this issue?

First.....it is difficult from the photo to identify the wire (wires) and it is difficult to determine if a wire was pulled completely. Pull the Plug, Remove the pins, solder the suspect wires to the correct pins, re-insert the pins.

But first find out what the owner (former owner) was attempting to do.

I guess I'd figure out what wire that is, then guess what they were trying to do when they cut it, then decide next steps.

On edit: What Dynomite said. :-)

The wire looks to have been cut, then put back together with some tape to hold it. The wire is green/white.

I would unpinit from the harness plug. Make sure the splice is ok then heat shrink wrap over the area. Re pin it. Not much else you can do.

It appears that the wire is long enough to re-establish the connection without the splice.

Yep possibly

The green/white if that's the actual color looks to only be used in A17, A19 of connector A. A-17 (817 - A VSS signal CCM/ETC) & A-19 (fuel pump relay driver).

FSM 6E3-A-13 for connector pin-out.

6E3-A-12 for circuit 817 A-17 routing explained and NOW MAYBE A FSM ERROR and an explanation, A19 is maybe misidentified as A1 on 6E3-A-7 for circuit 465 fuel pump relay driver. I checked a '90 and a '92 and it's identified as A19 on both routing explanations.

On 6E3-A-6 A1 is correctly ID'd as A1 (black circuit 841 INJ CONTROL) in the '91 FSM.

If the pinning is secured and you have no functionality issues maybe just clean up the splice (confirm all strands are utilized) and use some appropriate heat-shrink to pretty it up. Recreating the pinning might be overkill if the cars a driver. You know it's there and if you had issues with whichever circuit you know where to go. You start twisting/tweaking connectors you could create worse.

OP - I assumed you have the FSM. If not I could post all pages that I've mentioned.

It happened to me a few weeks ago and I posted a thread about this.

The local car electric shop charged me $20 to fix it. "Hardest" part was to search in the FSM to find in which hole the wire goes.

WVZR-1 · 05-06-2016

OP - did you ever determine which pin location was actually cut-spliced. Your situation is different from the previous post in as much as it would seem the PO (or someone) was attempting something. Either maybe fuel pump diagnostics OR perhaps they had thought they could use the ECM VSS output for an ERA/DRA for speedometer correction. Does the car have a rear gear change?
