Thread: ecu harness flushing ideas.

The biggest aid to the problem is the fact that the male section is in the head and the female part is the lower "catch cup" and the spare unused pin holes in the connector direct the flow into the harness.Its not possible but simply reversing this connector would allow the oil to leak out over the connector rather than pooling in and draining internally.
Keep up your posts Im sure with the combined brains trust here we will get a simple solution.Once mine is clean Im willing to risk cutting the harness and fitting an extra connector.My Mrs is an ex-electronics assembler so should be able to do it.

The reason I thought I would go the 'box' way was for a couple of reasons

1. You can mount the connectors on the box, keeps it neat
2. The box would offer some method on fixing to something so it didn't just flap around
3. Instead of the excess oil dripping anywhere - it could be directed to a tube fitted to the box and run to a suitable location where when you looked you didn't need to ask where is that bloody oil coming from.

If your misses has that experiance - I am a bit ham fisted, might be the better wat to go. I'll get something down on paper and post it here.

Hi All
I have done a little more research into the harness issues and found the following.
1.Thank you for your inquiry about Permatex products.
You will not have a concern when using Synthetic motor oils in place of standard mineral based oils in regards to Permatex Gasket Silicones. Test conducted by Permatex where Silicone samples have been emersed in oil which is far beyond the conditions found in a motor have shown some minor reduction in the products rigidity, flexibility and elongation. However the products properties were still well above the requirements needed in even the harshest service environment. This cannot be said about all silicones on the market.
For your particular job I would use Ultra Black as it has the greatest flexibility and oil resistance.
Ultra Grey is best for High torque applications (transmissions)
Ultra Copper is for High Temp. (exhaust manifolds)
Ultra Blue which was the original is now regarded as a general purpose gasket silicone, Pretty good for any job as long as it is inside the temperature range.
I have attached some TDS files on each product for your information.
If you would like more information or product catalogues please feel free to contact me with your postal address.
